Fringe field-based capacitive proximity sensors are well-suited to detect the presence of both conducting and nonconducting objects. The configuration of electrodes within these sensors significantly ...

Pyroelectric infrared sensors (PIR) are excellent devices to detect human/animal presence with a small form factor and rugged design, for cost-effective surveillance. They are widely used to trigger ...

Swiss scientists have developed perovskite image sensors that triple light capture, sharpen resolution, and outperform traditional silicon.
