In this letter, we examine the potential of a functional device that can have good transistor and stress sensor properties. The device examined is based on the use of a thin oxide with high piezoelectric coefficients under the gate region. Channel charge and current are controlled by gate voltage or by stress. We examine the performance of two classes of heterostructures that are important semi...

Abstract Field‐effect transistors have strong applications in biosensing field from pH and glucose monitoring to genomics, proteomics, cell signaling assays, biomedical diagnostics general. Notable advantages are the high sensitivity (thanks intrinsic amplification), quick response (useful for real‐time monitoring), suitability miniaturization, compact portable read‐out systems. The initial con...

We demonstrate the temperature mediated applications of a previously proposed novel localized dielectric heating method on the surface of dual purpose silicon field effect transistor (FET) sensor-heaters and perform modeling and characterization of the underlying mechanisms. The FETs are first shown to operate as electrical sensors via sensitivity to changes in pH in ionic fluids. The same devi...

Abstract Ion-sensitive field-effect transistors (ISFETs) have gained a lot of attention in recent times as compact, low-cost biosensors with fast response time and label-free detection. Dual gate ISFETs been shown to enhance detection sensitivity beyond the Nernst limit 59 mV pH ?1 when back dielectric is much thicker than top dielectric. However, back-dielectric limits its application for ultr...

A new atropine drug-FET sensor, which was made of an ISFET (ion sensitive field effect transistor) and a drug sensitive membrane prepared by adding electric active matter to a β-cyclodextrin solution, was developed. The pH influence, selectivity, response curve, reproducibility, stability, response time and life of this sensor were investigated. A preliminary application of the sensor was discu...

This study proposes a bidirectional chemical sensor platform using ambipolar double-gate ion-sensitive field-effect transistors (ISFET) with microwave-assisted Ni-silicide Schottky-barrier (SB) source and drain (S/D) on fully depleted silicon-on-insulator (FDSOI) substrate. The SB S/D offer turn-on characteristics for both p- n-type channel operations. operations are characterized by high noise...

Cava is a quality sparkling wine produced in Spain. As a product with a designation of origin, Cava wine has to meet certain quality requirements throughout its production process; therefore, the analysis of several parameters is of great interest. In this work, a portable electronic tongue for the analysis of Cava wine is described. The system is comprised of compact and low-power-consumption ...
