Gold plated disk shaped electrodes and spring probe electrodes built up two different kinds of sEMG electrode array; The conditioning circuit amplifies and filters the signal form electrode array; The data acquisition part converted the conditioned signal to digital for display and storage.

Based on voltage-polarity-related EWOD phenomenon,a novel single-side coplanar electrodes array digital microfluidics is designed and fabricated.

A simulated device was designed to study the crevice corrosion behavior of printed circuit board(PCB),and array electrode technique was established to measure the corrosion potential of copper in the crevices of the PCB immersed in aqueous NaCl and investigate the effects at various factors on the crevice corrosion behavior at the copper.

This paper introduces the basic principle of electrical capacitance tomography(ECT)system,and analyzes the effects of the structure parameters of array electrodes on the sensitivity distribution using finite element method(FEM),and also makes optimum design.
