Not all superheroes wear capes. Some wear vests.
When Joel An saw his mom struggling to walk safely across the room, he didn’t just sit with that feeling. He started building something to help his mom—a smart vest designed to support balance. But what he built has ended up helping a lot more people—those living with Ataxia, Parkinson’s, or anything else that throws off your balance.
This isn’t some futuristic gadget. It’s real. It’s been tested. And it might give people a little more freedom in how they move through the world.
From Family Struggle to Real-World Solution
Joel’s mom has Ataxia. He’s seen firsthand how it messes with your balance and coordination—and how it slowly chips away at your confidence. One step turns into a stumble. One fall changes everything. And suddenly, walking across the room doesn’t feel so simple anymore.
But Joel didn’t want to sit by and watch. So, he built something… and it worked.
Over time, with input from researchers, therapists, and other users, the idea evolved into a company: Anchor Logics, and a product: the PIEZO vest—a wearable, intelligent device designed to help users stabilize themselves during movement.
So, what is it? It’s a smart vest. One that helps people stay more balanced and avoid falls. It’s not bulky or awkward. You wear it like any other vest, and it quietly responds to your body’s movements in real time. That’s a big deal!
How the PIEZO Vest Works
The PIEZO smart vest uses small sensors and subtle vibrations to cue the body during movement. Here’s what makes it stand out:
- AI-powered sensors: detect sway and subtle shifts in posture.
- Real-time feedback: helps guide the wearer back to center without external input.
- Vibrations cue directional correction: how a balance therapist might physically guide someone.
- A companion app: allows users and caregivers to track patterns, fall risks, and improvements over time.
It’s not like using a cane or a walker. You’re not announcing anything. You wear it, and it quietly helps you stay steadier. Nothing flashy. Nothing in the way.
For people with Ataxia—or anything that messes with balance—that kind of subtle support can matter.
Trial Results: Evidence That It Works
This isn’t just a cool idea someone dreamed up. They tested it with real people, in real-world situations. And it worked.
- 214 participants were involved in the initial testing phase, including people with Ataxia, Parkinson’s disease, and post-stroke balance disorders.
- A 37% reduction in fall risk was observed across participants who used the vest.
- Users reported feeling more confident walking in public, with less fear of falling.
According to Berkeley Haas News, which featured the project in a 2024 article, the device is gaining traction in medical and rehabilitation communities. It’s not a gimmick—it’s a breakthrough.
This Isn’t About a Vest. It’s About What Happens When We Care.
When I first came across this story, it hit home. Living with Ataxia, I know what it’s like to second-guess your own footing. To pause before taking that extra step. To wonder if asking for help—again—is starting to wear people out.
What stood out to me most was that Joel didn’t try to fix everything—he just saw something that wasn’t working and tried to make it better. Not for attention. Just because he cared.
He built it for his mom. And now it’s helping other people too.
This vest won’t solve it all. But it’s proof that you don’t have to wait on some big breakthrough or system change to make a difference. Sometimes it starts with one person trying something new and following through.
Would I Use This?
If something like this helps me feel a little steadier—without making it obvious or getting in the way—I’m open to it.
And I’m pretty sure I’m not the only one who would be.
Final Thoughts: Confidence You Can Wear
Balance issues don’t always show until something goes wrong. And when they do, it’s not just about falling—it’s about what that fall takes from you. Confidence. Freedom. Options.
The idea behind this smart vest isn’t flashy. It’s just smart. It’s a way to give your body a little help without needing someone right next to you all the time. That’s what I like about it. It’s not trying to fix everything—it’s just trying to make things a little more manageable.
And honestly, that kind of thinking? We could use more of it.
This is part of the Steady Steps series—a collection of real stories, practical tools, and grounded reflections for people living with Ataxia or other conditions that affect movement, health, and daily life.
If this resonated with you, I’d love to hear your thoughts. And if you know someone who could use this kind of tech—or this kind of reminder—please share it. We’re building wellness and awareness, one steady step at a time.

Wow! What a great idea. As a person with Ataxia, I’m thrilled to hear about this innovative vest. It could make my solo walk (on the sandy beach) possible again. Thanks Joel and Michael!
