8Power Vibration Energy Harvesting Technology Powers Batteryless LPWAN GPS Trackers, MEMS Sensors

While IoT products usually promises one to 10 years battery life, they will be several billions of them, and ARM’s CEO even forecast one trillion IoT devices in the next 20 years. Recharging batteries at home may be fine, but imagine having to recharge or replace batteries on top of electric poles, inside walls, in remote locations, and other hard to reach places, considerable resources would have to be deployed just to replace or recharge battery every year or whenever the battery is close to being depleted.  That’s why work on energy harvesting technology for batteryless devices may be so important, and 8Power is one of the companies working in the field through their vibration energy harvesting technology that is said to harvest up to 10x the power of competing devices under comparable condition thanks to the use of parametric resonance phenomenon.

The company has recently announced their Track 100 family of LPWAN GPS tracker, such as Track 100XL relying on LTE NB-IoT, but they also have models supporting LTE Cat M1 and LoRaWAN. The IP67 devices include vibration energy harvesting technology, as well as optionally a solar panel. The company also provides a “secure cloud hosted data platform to provide dashboards, analytics, device management, security and application API access to manage fleets of devices”. There’s no battery, and no need for (battery related) maintenance. Track 100 trackers are powered through the vibration generated by trucks, trains, or other vehicles.

The company is also working on integrating the technology into MEMS sensors that consume very little power (10 mW) in continuous operations. Beside leveraging vibrations from the transportation industry, and 8Power technology can also generate power from vibrations from  infrastructure (bridges, embankments, transmission lines) or machinery (high-power motors and rotating equipment), and the technology has already been validated through a experiment to monitor the structure of an older bridge in Scotland.

The company showcased their technology and latest products at IDTechEx 2017.
