The $50 sensor runs on two coin cell batteries so you don’t need a nearby power source for installation.

Researchers created the first ultra-low power temperature sensor using graphene solar cells, a step toward long-lasting, self-powered devices for the Internet of Things.

One of the things that researchers and designers hope to achieve are sensors that can gather power from their environment rather than needing a battery. Batteries eventually run down requiring ...

ABLIC’s battery-less water leak detection sensor extends the communication range by approximately two times that of its ...

The internet of things is a nice idea, but there's one big catch: you have to power all those smart devices, which is no mean feat when some of them might not even have room for a battery. Dutch ...

An Intelligent Battery Sensor (IBS) is a mechatronic component that monitors and measurers battery performance, also called a battery current sensor. An IBS provides reliable information on key ...

Great hope has been invested in the technology of electric vehicles (EVs): it is expected to reduce greenhouse gas (GHG) emissions, promote sustainable energy development and improve air quality in ...

Samsung announced the Galaxy Watch 5 and Watch 5 Pro on Wednesday, giving its round, semi-rotating Wear OS watches new looks, a tougher screen material, and—for reasons the company can only vaguely ...

The first lithium-ion battery has been developed that shuts down before overheating, then restarts immediately when the temperature cools. The new technology could prevent the kind of fires that have ...
