Batteryless, Autonomous, LoRaWAN tracking devices
summary
Claims a working battery-less LoRaWAN tracker that runs on harvested energy and supercapacitors rather than rechargeable cells, using an EPS energy‑harvester chip with a 0.4 Wh flat supercapacitor (and cylindrical types) to tolerate wide temperatures. Hardware combines STM32WL LoRa + u‑blox GPS with Wi‑Fi/BLE for positioning and USB‑C for topping up. Experiments show self‑discharge <1%/month, a 4 W solar locator running continuously, and 700+ cycling air monitors deployed, indicating the approach actually works in the field.
