Implementation of capacitance as simultaneous sensing and actuating tool in tapered microelectrode arrays for dielectrophoresis-on-a-chip application
Purpose: This paper aims to present the capacitance characterization of tapered dielectrophoresis (DEP) microelectrodes as micro-electro-mechanical system sensor and actuator device. The application of DEP-on-a-chip (DOC) can be used to evaluate and correlate the capacitive sensing measurement at an...
