Electrostriction enhancement of solid-state capacitance sensing

Suspended Solid-state Membranes on Glass Chips with Sub 1-pF Capacitance for Biomolecule Sensing Applications

Solid-state membranes are finding use in many applications in nanoelectronics and nanomedicine, from single molecule sensors to water filtration, and yet many of their electronics applications are limited by the relatively high current noise and low bandwidth stemming from the relatively high capacitance (>10 pF) of the membrane chips. To address this problem, we devised an integrated fabricati...

Interferometric investigation of quadratic electrostriction in solid dielectrics

Electrostriction Is the strain response of a dlelectric material proportional to the square of an applled electric field. Thls effect Is related to 1he straindependence of 1he dlelectric function. The strain signal observed using optical inlerlerometry is a superposition of true electrostriction and other effects llke electrostalie lorces and thennal stresses. Therelore, ~Is necessary to have a...

Electric field detection using solid state variable capacitance

Operation of traditional fieldmeters typically relies on mechanically actuated capacitance for DC fields measurement. This paper provides theoretical background for operation of an electric field sensor with a solid state variable capacitor. Design is supported by circuit and FEA models, illustrating the operation. Theoretical work is verified against results of sensor’s tests performed in DC, ...
