When light strikes the photodiode’s active region, current flows from cathode to anode. Ideally, this entire photocurrent ...

Capacitive sensing is a versatile sensor technology and has proven itself in many different measurement and detection tasks [1]. The measurement principle is based on the capacitive coupling between ...

Research on pressure sensors using elastic materials is actively underway to develop next-generation devices for applications in healthcare monitoring, haptic sensors, and electronic skin.

One application of this phenomenon is integrated resistive-capacitive strain sensors, which show potential in e-skin applications. A reusable e-skin switch was tested at a person’s knuckle.

A device/circuit mixed-mode simulation method is proposed to effectively characterize the physical effects of the structure parameters and external noise signals on the sensing performance of ...
