Humidity sensing behavior of silicon nanowires with hexamethyldisilazane modification

Memristive Biosensors Under Varying Humidity Conditions

“…Silicon nanowires show in itself a relevant dependence on humidity [30], [31]. In fact, due to to the large surface-to-volume ratio, they present a large amount of hydroxyl groups that enable the adsorbtion of more water molecules.…”

Fabrication of superhydrophobic and superoleophilic textiles for oil–water separation

“…These gels containing abundances numbers of -OH groups on their surface were reacted with HMDS to convert a major amount of the OH groups to Si(CH 3 ) (trimethylsilyl) according to the following reaction (Eq (2)) [28] 2 − OH + (CH 3 …”

High sensitivity and fast response graphene oxide capacitive humidity sensor with computer-aided design

“…Here we present a computer-aided design to predict the transient response and steady response of these capacitive sensors. We find that humidity sensors based on GO can overcome the existing problems reported in literature [23][24][25][26][27][28][29][30], and exhibit ultrahigh humidity sensitivity, as well as short response time. properties of the presented sensor are investigated over a wide range of 0-100% relative humidity at room temperature.…”

“…Water molecules are absorbed on a solid surface through chemisorption or physisorption, and the conditions in which they occur vary. At low RH, chemisorption play a major role, water molecules cannot move freely, they are always doubly bonded to two hydroxyls of the surface, that makes respond time shorter [23,39]. Concentration distribution of adsorbed water molecules at the initial stage is illustrated in Fig.…”
