Tiny heat pump that relies on changing ambient temperature could be key to powering IoT devices and sensors without batteries forever — Nanoparticles are critical to the process, posit scientists


As IoT technology progresses, the question of how to power these devices, particularly in locations where reliable electrical sources are scarce, presents a significant challenge. 

Researchers at the University of Utah’s College of Engineering have pioneered a new form of battery that could help solve this dilemma. The solution, which is at the proof of concept stage, comes in the form of a pyroelectrochemical cell (PEC).
