RH sensors have been made using porous polysilicon and porous SiC, both of which can also be made porous by electrochemical anodisation in HF, similarly to single crystal silicon. We show that polysilicon can be incorporated into a humidity sensor enabling a reduction (compared to single-crystal porous Si) of the effect of temperature on humidity measurements. We show that also porous SiC can a...

In this paper, the performance of a zinc oxide (ZnO) nanorod-based enzymatic glucose sensor was enhanced with silver (Ag)-doped ZnO (ZnO-Ag) nanorods. The effect of the doped Ag on the surface morphologies, wettability, and electron transfer capability of the ZnO-Ag nanorods, as well as the catalytic character of glucose oxidase (GOx) and the performance of the glucose sensor was investigated. ...

In this paper, we present the effect of varying humidity levels on the electrical parameters and the multi frequency response of the electrical parameters of an organic-inorganic composite (PEPC+NiPc+Cu2O)-based humidity sensor. Silver thin films (thickness ~200 nm) were primarily deposited on plasma cleaned glass substrates by the physical vapor deposition (PVD) technique. A pair of rectangula...

a feasible and fast method to fabricate hydrogen peroxide sensor was investigated by graphene-manganase nanocomposite carbone paste electrode. in the present work, in first step, the graphene was synthesized by chemical method and in second step, manganese oxide nanoparticle was doped on graphene. graphene-manganase nanocomposite was characterized by ftir and sem. the nanocomposite shows a high...

Ionic polymer-metal composites (IPMCs) exhibit humidity-dependent sensing behavior when operating in air, which weakens the reliability of the IPMC sensors. To better understand the underlying physics of this behavior and capture the humiditydependence analytically, in this paper the influence of the ambient humidity on IPMC sensors is characterized and modeled from a physical perspective. In p...
