Capacitive sensors work by detecting the change of capacitance introduced by the finger touching near the electrode. Such change is so small that detecting it unambiguously is challenging, and has ...

How to build a circuit that converts capacitance into a pulse train. Test results of the circuit design. The circuit in Figure 1 allows you to convert capacitance into a pulse train by using a ...

Abstract: Capacitive Micromachined Ultrasonic Transducers (CMUTs) are the prospective alternative to the traditional piezoelectric ultrasonic transducers. CMUTs are essentially parallel plate ...

A new study has unveiled a new method for wirelessly powering implantable medical devices (IMDs) using a pre-charged capacitive micromachined ultrasonic transducer (CMUT). Unlike traditional systems ...

Most touchscreen panels have a limited type of haptic feedback or none at all. This is also true for many types of handheld or wearable devices like watches, touchpads, keyboards, a mouse, etc. The ...
