PDMS-Coated Piezoresistive NEMS Diaphragm for Chloroform Vapor Detection [PDF]

IEEE Electron Device Letters, 2012
A polydimethylsiloxane (PDMS)-coated nanoelectromechanical systems diaphragm embedded with silicon nanowires (SiNWs) is proposed for chloroform vapor detection at room temperature. The PDMS film swells and leads to the deformation of micro-diaphragm when it is exposed to vapor.

Hydrogel‐Based 3D‐Printable Stretchable Pressure Sensor

Advanced Materials Technologies, EarlyView.
We present a carbon‐black‐functionalized double‐network granular hydrogel (DNGH) pressure sensor capable of detecting pressures from 200 Pa, equivalent to a light finger touch, up to 500 kPa. The sensor exhibits signal drifts below 3.5% after 800 cycles and response times around 80 ms. Leveraging this broad sensing range, we 3D print this material into
