Abstract: | Inter-digital capacitive electrodes working as electric field sensors have been developed for
touch panel applications. Evaluation circuits to convert variations in electric fields in such sensors into
computer compatible data are commercially available. We report development of an Interdigital
capacitive electrode working as a sensitive pressure sensor in the range 0-120 kPa. Essentially it is a
touch/proximity sensor converted into a pressure sensor with a suitable elastomer buffer medium
acting as the pressure transmitter. The performance of the sensor has been evaluated and reported.
Such sensors can be made very economical in comparison to existing pressure sensors. Moreover, they
are very convenient to be fabricated into sensor arrays involving a number of sensors for distributed
pressure sensing applications such as in biomedical systems. |
