Elimination of shunting conductance effects in a low-cost capacitive-sensor interface
A low-cost and reliable interface for capacitive sensors, based on the use of a relaxation oscillator and a microcontroller, is presented. The novel interface system is designed to measure small capacitances in a reliable and accurate way even when the sensor capacitors are shunted by parasitic conductances. The problem of shunting conductances is solved by performing a series of eight measurem...

متن کاملDesign of Novel High Sensitive MEMS Capacitive Fingerprint Sensor
In this paper a new design of MEMS capacitive fingerprint sensors is presented. The capacitive sensor is made of two parallel plates with air gap. In these sensors, the capacitance changes is very important factor. It is caused by deformation of the upper electrode of sensor. In this study with making slots in upper electrode, using T-shaped protrusion on diaphragm in order to concentrate the f...
متن کاملJack-on: a low-Cost Wireless Sensor Interface
JACK-ON is a wireless sensor interface using sine tone oscillators. Sensor resistances alter oscillator frequencies or amplitudes, and the audio output of oscillators is sent through a generic wireless audio transceiver. The wireless audio receiver is plugged into the computer’s sound card, where oscillator frequencies and amplitudes are analyzed in software. Thus, analog to digital conversion ...
