The capacitive sensing electrodes on the top of a CMOS chip serve as an interface between the microelectronic readout system and the biological/chemical analyte. These electrodes are directly exposed to the analyte or an intermediate layer which will be described in Chapter 3 (Fig. 2.1). The sensing electrode can be realized by a standard CMOS process.

Capacitive Stretch Sensing for Robotic Skins
Soft Robotics, 2019Various types of artificial skins have been developed to provide robots with a sense of touch. Because of their compliance, dielectric elastomer (DE) capacitive sensors are particularly suitable for soft robots. Although the electrodes of DE sensors exhibit nonlinear effects such as transient resistance changes and resistance peaks, this does not ...

Label-free capacitance DNA sensing
2013 Seventh International Conference on Sensing Technology (ICST), 2013This paper presents the use of direct capacitance measurements for label free hybridization detection of ssDNA immobilized directly on a gold interdigitated array of microelectrodes (IDAM). Thiol modified 18 bases long Poly-dT ssDNA molecules were immobilized on the Au IDAM surface without the use of any isolative self assembled monolayer (SAM ...
