The method for group manufacturing of pyroelectric sensors by forming a thin pyroelectric layer on the upper side of a silicon wafer, where each sensor comprises several pixels (4) and each pixel is defined by an upper electrode (6) situated on the face si ...
A systematic study was carried out to assess property changes in CaCu3Ti4O12 thin films upon annealing in air in order to evaluate the impact of oxygen vacancies on their colossal dielectric constant behavior. Highly preferentially oriented thin-film sampl ...
A point-contact model is presented, and an areacontact model has been analytically derived in order to model the electrical characteristic of the cell-electrode interface of high-density neuron cultures. The area-contact model is presented as a model more ...
A sensor for measuring adsorption on a substrate has been designed including a contactless detection scheme, called supercapacitive admittance tomoscopy (SCAT). The sensor comprises a thin dielectric layer with two parallel band electrodes on the one side ...

A device for monitoring the adsorption of target molecules on a substrate, the device comprising a substrate (1), at least a portion of which is formed as a thin dielectric layer. A first, modified surface (2) of the layer has ionizable groups of the subst ...

WC/amorphous carbon (a-C) thin films were deposited by dual magnetron sputtering from individual WC and graphite targets. The influence of film composition and microstructure on the optical and electrical properties was investigated. As evidenced by x-ray ...
This thesis presents the fabrication and design of an impedance imaging sensor, and its application to monitoring in-vitro skin culture. Three-dimensional tissue cultures are becoming increasingly important in biological and medical research. There is, how ...
We have realized a flexible force sensor, composed of four redundant capacitors, the operation of which is based on the measurement of a load-induced capacitance change. We use polyimide both as flexible substrate and as elastic dielectric between two leve ...
Accurate electrical models are needed to support the design of modern microelectrode arrays. The point-contact model is presented thoroughly, and an area-contact model is analytically derived in order to model the electrical characteristics of the cell-ele ...
We formulate a generalized tunneling-percolation model that describes the electrical properties of conductor-insulator cellular disordered systems. This model predicts and explains the experimentally observed universal and nonuniversal behaviors of such pr ...
