The paper discusses the importance and the issues of interfacing capacitive sensors. Two architectures applicable for interfacing capacitive sensors are presented. The first solution was designed to interface a capacitive humidity sensor designed and built for a humiditydependent monolithic capacitor developed at Budapest University of Technology and Economics. The second case presents the poss...

— This paper proposes a new circuit for capacitive sensing based on Dickson's charge pump. The proposed touch sensing circuit includes three stages of NMOS diodes and capacitors for charge transfer. The proposed circuit which has a simplified capacitive touch sensor model has been analyzed and simulated by Spectre using Magna EDMOS technology. Looking from the simulation results, the proposed c...

Capacitive technologies play an increasingly important role in the fields of industrial and automotive sensors. The noncontact working principle, on the one hand, is the main advantage of this technology; on the other hand, the sensor is thus sensitive to electromagnetic disturbances. This paper describes methods to successfully develop capacitive sensors, which can reliably be operated in hars...

A high accuracy switched capacitor, triple slope digital converter suitable for differential capacitive sensors is presented. The proposed technique accepts differential capacitive sensors possessing either linear or inverse characteristics and provides a linear capacitance to digital conversion. The output is dependent only on a pair of d.c. reference voltages and the clock frequency. Detailed...

A highly sensitive NEMS capacitive sensor with electrode separation in the order of Debye length is fabricated for label free DNA analysis. The use of nano-scale electrode separation provides better insight in to the target-probe interaction which was not previously attainable with macro or even micro scale devices. As the double layers from both the capacitive electrodes merge together and occ...

Amorphous electroless Ni-B coatings were deposited on steel substrates with different surface morphologies and B contents (6.5–8.64 wt.%) that could be changed by altering the temperature composition of baths. The supercapacitive behavior was evaluated cyclic voltammetry galvanostatic charge–discharge measurements, it found had higher capacitance than pure Ni or bulk plate. A close relationship...

<p class="Abstract">This research introduces the analysis and design of Class E-LCCL for capacitive power transfer (CPT) system. The CPT Class-E LCCL system is able to operate at high-frequency with decreased capacitance plate size reduced losses by minimising switching losses. Additionally, a amplifier less complicated, since it usually lighter smaller comparative intolerance different c...
