Gosh, my neck, my back, they hurt so bad from my poor posture. If you're just like me, you're not alone, right? Poor posture is impacting millions of people around the world. And if your back hurts from poor posture, the way that Farbod and my back hurts from carrying the podcast game, you're going to want to check out this episode. Cause we're talking about a startup called StraightUp. That's making a wearable device to help you correct your posture over time.

I'm Daniel, and I'm Farbod. And this is the NextByte Podcast. Every week, we explore interesting and impactful tech and engineering content from Wevolver.com and deliver it to you in bite sized episodes that are easy to understand, regardless of your background. 

Daniel: What's up folks? Like we said on today's podcast episode, we're talking all about back pain and neck pain, which is a widespread issue. And this basically fledgling startup of students from Karlsruhe Institute of Technology, KIT, they made a startup called StraightUp. That's StraightUp gonna fix your back, StraightUp gonna fix your neck problems and make sure that you're StraightUp, standing StraightUp and sitting StraightUp all the time because I don't know, I think it's awesome the way that they've used technology in this sustainable user-friendly approach. I don't want to jump too fast into it. Maybe we talk a little bit more about the why first, but I think it's StraightUp interesting.

Farbod: I StraightUp agree with you. And I think I'm very relevant to the why. They talk about how in the Western world, our sedentary life has led to us having a lot of back problems, a lot of neck problems. And then, a lot of people don't exercise a lot. So, I'm gonna call myself out from 8 a.m. today. It's almost 8 p.m. now. I have basically been slouched on the couch looking at a monitor. And even right now, like I had to straighten up as you started talking about the topic. My back has just kind of been hunched over. You know, I'm a youngish man right now. So, the effects have been somewhat minimal, but I feel like if I don't correct this, it's gonna catch up with me and I'm gonna feel the pain down the road. Now, Daniel over here, he's already ahead of the curve. This man is religious about his standing desk. So, he obviously has no idea what the rest of us in the Western world are talking about.

Daniel: I know exactly what you're talking about. This is exactly why I stand up every day when I'm working at my desk, because I do have back pain. I do have neck pain from sitting on the couch or sitting in a chair and slouching. And my dad, like, had to have like really invasive back surgery and all this stuff. And he says a lot of it is probably because of his sedentary office environment, lack of movement during the day, poor posture, created a chronic issue in his back that could only be fixed by surgery. So, I'm trying to take some preventative measures along the way, but I still think there's a lot that I can do to improve my posture. And what's crazy is like a vast majority of back pain and back surgeries, chiropractor visits, et cetera. Doctors contribute a vast majority of those actually to just people's posture, right? Something that you do every single day, you know, 99 plus percent of the time, whenever you're sitting in a chair, staring at a screen or staring at your phone, that creates a lot of long-term impact on your body. And the traditional solutions for posture correcting either restrict your mobility. Right. They feel like you're like strapped into something or there's even like these new startups trying to think of one, I think it's called Upright. Which is crazy because this one's called StraightUp. So maybe they've got some beef already. But Upright is something that I've seen a lot of Instagram ads for. And it basically looks like about something about size of an AirPods case. And it hangs on a necklace on your back and it's supposed to like vibrate and let you know when you've bent over too far like you're slouching a little bit. But one of the challenges with that, and I've actually, no joke, like I'm not trying to just show StraightUp here. I've actually like looked into it and saw people on Reddit saying like, this thing's so freaking annoying. It vibrates like whenever I bend down to pick something up off the ground, I'm like, I'm not slouching. I'm just literally picking something up off the ground. So, traditional solutions either restrict your mobility, you're in a brace or they give inaccurate feedback during common most common movements. So, both of those, less effective than they could be. So, enter this team straight up, spin-off from Karlsruhe institutes at technology, I think it's three students.

Farbod: Three students and a physiotherapist. Yeah.

Daniel: And a physiotherapist from KIT, right? They're teaming up to try and tackle this problem with a more user-friendly approach. And this more user-friendly approach is correcting posture using haptic feedback. So, for those of you that don't know what haptic feedback is, that's like when you're typing on your phone and it vibrates a little bit, or you press a button on your phone and it vibrates a little bit, lets your body know with a physical response that the way it's interacting with something. So, in this case, the way you interact with this device is it does small vibrations, haptic feedback, to let you know when you have bad posture, to try and remind you, hey, it's time to maybe put your shoulder blades back a little bit and straighten out your neck. That gives you a little bit of a vibration as a reminder for that. It's not very restrictive like a brace. And essentially, it's this wearable that helps correct your posture. It measures your shoulder position, measures your back inclination, measures the position of your neck and tries to help encourage you to learn healthy posture. And that's one of the challenges, let's say with like a normal back brace right now to try and fix this. And Nellie even bought a posture corrector and had the same complaint, which is like, it feels like it's forcing my body to be in the right position rather than teaching it to be in the right position. So, the second you take it off, your body hasn't learned to make this its new natural home. You just go back to slouching like you were before, and it just feels kind of uncomfortable when you're wearing it. So instead of forcing your body to be in the right position, it's slowly teaching it and encouraging it with haptic feedback to maintain proper posture.

Farbod: Yeah, and I mean, we can kind of start jumping into their solution, but they kind of got the best of both worlds figured out. On the material side, they chose this elastic metal alloy. So, as the name implies, it's made of metal, but it's elastic so it can conform to your body. So, it's not super rigid. Instead of having a, you know what you were talking about, I think Upright, I don't know how Upright technology works. I'm guessing that little necklace has some sort of sensor that says if you've been tilted this much, give it vibration. These folks over at StraightUp are using an AI, which I am guessing takes into account a bunch of different feedback from the harness to then say, yeah, this person's actually been crouching over their computer for an extended period of time versus, oh, they're just bending over to pick something up, or maybe they're playing a sport. And just being able to differentiate between what your body's doing in different conditions instead of a binary, oh, you're in a bad posture, or no, you're in a perfect posture.

Daniel: Yeah, I think this is like the more nuanced next generation version of some of the things that we've seen before. Not to dog on Upright at all, right? It's a great idea. But this feels like almost like an extra twist on that, that uses these, they call them conductive super elastic metal alloys, which basically in my mind, my interpretation of this is they've got these metal wires that are weaved into the fabric of this harness that avoids all the bulkiness of having external components like an accelerometer or something like that. And what it does is it flexes with the user's movements and because it's super stretchy and because they also mentioned it's conductive, I’m imagining all they're doing is measuring the resistance of this wire and as the person changes position the resistance of the wire changes as it stretches or contracts with the body. And that allows them to gain a lot of insight on the body's position and then that allows them to you know use their AI process or whatever using the sensor data to distinguish between a normal forward bending motion versus harmful slouching. And then give the person direct haptic feedback. So, instead of locking your back into a rigid position, like a brace, what are giving you errant feedback, like some other solutions do, it tries to make sure that it knows exactly when you're holding bad posture, gives you a subtle vibration to try and train your body, say, oh, I actually have bad posture. I'm going to put my shoulders back. I'm going to straighten out my neck a little bit and it promotes you actively correcting your posture. Building better muscles to stabilize your shoulder blades in your spine and your neck as opposed to like forcing your body to do it or giving you too many notifications. So, you do it at the wrong time.

Farbod: Yeah. And that in itself is already pretty promising. What I found to be even more impressive is that it looks like they're now working with the German Institute for Textile and Fiber Research. I'm guessing they're doing this to better understand how they can kind of merge this technology into a shirt or something that you would just wear. So, it's not like a separate device. And that is like, it just kind of plants the seed in my brain where I'm like, if you're able to extract that much information about posture, could you then make this a wearable that assist folks that are doing general physiotherapy and getting their movements in to heal from some sort of injury? Or for the average Joe on a day-to-day basis, could you use that to collect health data and provide, I don't know, more detailed feedback in terms of how your muscles are responding to different stimuli?

Daniel: That's exactly where my brain went to man. Like Nellie and I are, we're in the pain cave right now for marathon training. Like we're in the thick of it. We're a couple of weeks out from the marathon race and we're dealing with some nagging injuries. And one of the things that they say potentially a lot of these injuries stem from is like poor form, poor running form, which is basically just your posture while you're running and then overuse of your muscles in that poor posture and I went exactly there too, man. I'm like, well, this is just focusing on posture of your neck and shoulders. What if there were other, I could put on a different type of harness or belt that looks at the posture of my hips and my glutes and my legs during my running, or look at the pronation of my feet, socks that look at the pronation of my feet during running and try and give me active reminders to correct my form and do it in a proper way. Also think about like lifting weights. People get hurt all the time lifting weights because they're doing it with the wrong form. They put on too much weight, they're trying to be strong, and then they do it the wrong way, and then bang, they injure the rotator cuff in their shoulder. Like there's a lot of other types of posture, not just the one that's when we're sedentary at our desk, that matters a lot to how our bodies perform and recover and interact with the world around us. I think that straight up starting with this, but they could absolutely apply this technology to other types of applications and get similar results.

Farbod: Me too. It's crazy that you and I both went to the same spot given that I spend most of my time in a chair and you spent most of your time getting ready for a marathon. So, great minds think alike despite how lazy they might be.

Daniel: I don't, I think I'm an equal amount of lazy. We're just, we're signed up for it. We're committed at this point, going to try and make it across the finish line. But I do want to mention, I think in terms of pros and cons. This wearable definitely could help lots and lots of people. I don't know from an adoption perspective; how many people are gonna be more willing to put this thing on. It looks a little bit more like a bra, like a harness than it does like a necklace. Feels a lot easier to try and convince someone like, oh, put on this necklace versus like put on this harness every single day. That being said, it does look like it's pretty sleek. Does look like it won't, you don't have to wear it over your clothes and it does look like it would be pretty form fitting. So, I think that that's interesting. I would be interested in how many, how many people of the millions of people suffering from posture related back pain would be willing to adopt this. But that goes to my pros, which is like, it seems like they've challenged, they overcome a lot of the challenges with AI based feedback system. Seems like they've overcome a lot of the challenges related to sustainability, right? Using haptic feedback and encouraging the person to use the right posture instead of forcing them to use the right posture. That feels like it's more sustainable. Having sensor accuracy in diverse environments, right? You want to get reminded to have correct posture when you're sitting. You maybe don't care too much if you're bending down to pick up the pencil off the ground. Like those, that's crucial in real world use. I would love to see how this compares with a competitor like Upright. And we've kind of alluded to it a couple of times, but these folks have created their own company called StraightUp. I think based on their website, I was on it earlier today, they're planning on launching in Kickstarter in 163 days. They've got a countdown, which is pretty cool. So, we'll definitely be following you, StraightUp team. And we'd love to see how this, how this tech solution continues to evolve and develop and hopefully make it to market and make a lot of impact. I say this on so many podcast episodes, but my biggest pet peeve about technology is when someone develops it and it could impact a lot of people and then it sits on a shelf and collects dust. This team from StraightUp is doing the exact opposite, right? They're taking their technology and sprinting to market as fast as they can, which is something that I really, really appreciate.

Farbod: Yeah, and as a listener, if you're interested in something like this, make sure you check out their page, give them support as they launch. If you got feedback, it's a perfect time to just kind of get in on the ground floor and voice your opinions.

Daniel: Yeah, I'm with you. And well, in addition to the article, which we, every single time, link in the show notes, we're gonna also link StraightUp's website so you can check it out and check out some of their content and watch the countdown till the Kickstarter launch, the way that I'm going to for the next 163 days and 11 hours and 53 minutes and five seconds.

Farbod: If only it was before your marathon. Alas. All right, man, you wanna give us a quick wrap up?

Daniel: Yes, I do. Do your neck and back hurt after hours of slouching at your desk, staring at your phone? If yes, like Farbod and me, you're not alone. Poor posture is pretty much our modern-day epidemic. Millions of people in the world struggle with their back and their neck pain that's caused specifically by poor posture, but a lot of the solutions out there, like braces actually just limit your mobility instead of training your body to do the right thing. So, what if your clothes or a slim wearable could silently train you to sit and stand correctly all day long? Enter the startup called StraightUp. They developed a slim wearable device that uses AI and sensors woven into the fabric to help correct your posture with the gentle vibrations, just training your body, teaching your body over time to move and to hold the right posture. I think of this as like the Garmin for exercise or the aura ring for sleep, but this is for posture I wonder if one day millions of people in the world will be using StraightUp to move the posture game forward in the future.

Farbod: Money that was straight-up money.

Daniel: Thanks, dawg.

Farbod: Anytime. All right folks. Thank you so much for listening as always. We'll catch in the next one.

Daniel: Peace.
