This paper describes a capacitive type touch sensor readout circuit using passive sigma-delta modulator-based capacitance-to-digital converter. With the proposed approach, the panel condition (touched ...

We operated a Hall sensor using energy harvested from a magnetic wire. A batteryless sensor is expected to be a key device for the Internet of Things. Magnetization reversal in magnetic wires with ...
