A new self-powered water sensor uses wave energy to monitor pollutants like heavy metals, microplastics, and pesticides - no battery needed. The innovation integrates two core components. First, a ...

Liquid-level sensing based on capacitive sensors comes with its own challenges. It’s like absolute capacitance sensing. Unlike touch detection, the absolute value of the liquid level needs to be ...

They linger in our water, our blood and the environment—so-called "forever chemicals” that are notoriously difficult to detect. But researchers at the University of Chicago Pritzker School of ...
