Tests confirm graphene-based energy harvesters can use ambient energy to run ultra-low power sensors — the first hurdle in developing autonomous sensor systems.

The solar cells combine multilayer graphene with silicon wafers, harvesting both solar and kinetic energy for continuous operation. Tests show the cells can autonomously power supercapacitors embedded ...

An array of graphene-silicon solar cells provides enough power to continuously supply small devices unconnected from the ...

This article presents the possibility of designing a simple self-powered solar tracking sensor circuit. The complete circuitry is self-powered, since it uses only the power obtained from the ...

[Manish] packed lots of functionality into this radiation sensor module. The device is completely solar powered and weatherproof, so it can be mounted anywhere. It uses a Geiger Muller tube to monitor ...

Industry leading LoRaWAN sensor provider ELSYS is launching their first battery-free products using Epishine’s indoor light energy harvesting solution. The environmentally friendly sensor line is ...

It’s easy enough to find a solar-powered charger for iPods, cell phones, and other gadgets, but this ultra-tiny solar-powered sensor system is smaller than anything else on the market — 1,000 times ...
