[Thu Aug 27] What's Actually New in E-Textiles and ESP32 Right Now
Every so often it's worth lifting our heads up from the soldering iron and looking at where this whole e-textile and maker-electronics space is actually headed. Two things crossed my feed this month that I think are genuinely relevant to what happens on your workbench, not just industry press-release noise, so let's talk about them.
Smart textiles are having a real growth moment. Market research is pegging the smart textiles space at roughly $9.6 billion in 2026, growing at close to 29% a year, with healthcare monitoring, defense/safety gear, and consumer fitness wearables leading adoption. The part that matters for us hobbyists isn't the dollar figure, it's what's driving it: sensor-and-energy-harvesting fabric is moving from "cool demo" to "expected feature." Companies like Loomia are shipping smart fabric panels for touch and haptic feedback, and Hexoskin has been doing sensor-integrated health-monitoring shirts for a while now. When an industry moves like that, the materials that used to be lab-only get cheaper and easier to buy — which is exactly why we've been able to keep expanding our conductive fabric shelf.
If you've been meaning to experiment with soft circuits but weren't sure where to start, this is a good week for it. Our Black Conductive Fabric with Adhesive Backing (from $2.75 CAD) is the easiest entry point I know — no sewing required to prototype a trace, just cut and stick, then sew it down properly once you know the layout works. For anything that needs to survive real wear and washing, our ripstop conductive fabric (from $2.25 CAD) and nickel diamond ripstop ($3.10 CAD) are tear-resistant by weave, not just by luck, which matters a lot once a "prototype" becomes a "thing I wear to an event."
On the electronics side, Espressif's next-generation chip just went into mass production. The ESP32-S31 is shipping now, and it's a meaningful jump: Wi-Fi 6, Bluetooth 5.4, Thread/Zigbee radio support, and Matter compatibility, all in a chip aimed at the same DIY price range we're used to. I'm not going to tell you to rush out and redesign every project around it — the WROOM-32 boards we all know are not going anywhere, and most wearable projects don't need Wi-Fi 6 or Matter. But if you've got a project on the horizon that involves talking to smart home devices, or you want your build to have a longer relevant shelf life, it's worth keeping an eye on boards built around it over the next few months as they hit hobbyist retailers.
For most of what we build on this channel, though, the classic ESP32 remains the right, reliable choice, especially once you've got a stable PlatformIO workflow going. If you're newer to the ecosystem, our ESP32 Development Board 30-Pin (USB-C) ($14.95 CAD) is still the board I hand to students first, for exactly the "boring is good" reasons above.
The practical takeaway I'd leave you with: the wearable tech space is scaling up fast, but the fundamentals — a reliable conductive fabric, a well-understood microcontroller, a clean PlatformIO setup — are still what separate a project that works from one that looks good in a photo and then falls apart at the seams (literally, sometimes). If you want to see those fundamentals in action, our Wearable Simon Game Video Kit ($49.95 CAD, limited stock) combines conductive fabric touch pads with an ESP32 and WS2812B LEDs — it's a genuinely fun way to prove out soft-circuit skills before you commit them to a garment you actually care about.
What are you seeing in the space that I should cover next? I'm always looking for what's actually useful versus what's just trending on LinkedIn.
