The team at Truvami has just raised the bar for what an asset tracker can be. At The Things Conference 2025, we got hands-on with their latest device, a battery-free, flexible PCB tracker that’s designed for smart logistics, indoor locationing, and low-maintenance deployment in large-scale operations. This thing isn’t just smart—it’s solar-powered, sticker-thin, and packed with sensors.
Asset tracking has evolved over the years, from manual QR codes and gate-level RFID systems, to the rich, continuous data streams provided by battery-powered IoT trackers. But batteries are a headache at scale. If you’re running a warehouse with thousands of assets, managing device uptime and battery replacements is a full-time job. Truvami’s new tracker solves that by removing the battery entirely.
Instead, this tracker uses Dracula Technologies’ ambient energy harvesting tech to operate using nothing more than the overhead lighting in your warehouse. Power is stored in a tiny supercapacitor, giving the device days of backup runtime without light. It’s all built onto a flexible PCB, which allows the tracker to be affixed to curved surfaces like pipes, crates, or containers—ideal for tough industrial environments.
And this isn’t just a location beacon. Truvami has squeezed in a full sensor suite. The device includes an onboard temperature sensor, motion detection via accelerometer, and visual feedback through an LED. That means it can report when an item moves, how long it’s been idle, and whether environmental thresholds have been exceeded.
Data transmission is handled over LoRaWAN, with signal fusion from Wi-Fi MAC/RSSI values and assisted GNSS to enhance positioning accuracy. And integration couldn’t be easier—location and status updates are piped directly into your IoT backend via REST API, Kafka queue, or webhook. You don’t just know where your assets are—you know what they’re doing and if they’re safe.
The whole system is optimised for cost, flexibility, and context-aware intelligence. There’s no bulky enclosure, no battery to maintain, and no guesswork. Just peel, stick, and track.
This is exactly the kind of product we love to see at ipXchange—a small, smart solution that solves real problems for engineers deploying at scale.
