Super flexible sensor skin using liquid metal as interconnect

Microfluidic devices using flexible organic electronic materials

“…Hence, measurement of the resistance of the elastic conductor could be done as a strain sensor. For example, by encapsulating multiwalled carbon nanotubes (MWNT) into PDMS and a liquid alloy as interconnects, a strain senor was initially demonstrated (Hu, Kashan, & Liu, 2007). Recently, this design was improved by moulding on an elastic conductor made from carbon black and PDMS (Lu, Lu, Yang, & Rogers, 2012).…”

Conductive polymer-based sensors for biomedical applications

“…Consequently, research efforts are driven towards increasing the reliability and robustness of these traces. Hu et al (2007) reported a flexible sensor capable of sensing force and temperature simultaneously. The sensor comprised of a composite material (multi-walled carbon nanotubes dispersed in polydimethylsiloxane (PDMS)) and liquid metal interconnects.…”

“…In the past two decades, tremendous efforts have been towards developing a human-skin-like sensor that can potentially provide a broad spectrum of tactile information particularly useful in the field of medical robotics and certain surgical procedures (Beebe et al, 1995;Engel et al, 2003a,b;Hu et al, 2007;Jiang et al, 1997;Kane et al, 2000;Kolesar and Dyson, 1995;Reston and Kolesar, 1990;Sekitani et al, 2008;Shimizu et al, 2002;Someya et al, 2005;Yang et al, 2008). Different types of materials used for tactile sensing includes silicon-based piezoresistive (Beebe et al, 1995;Kane et al, 2000) or capacitive sensors (Gray and Fearing, 1996;Leineweber et al, 2000), and polymer-based piezoelectric, capacitive or piezoresistive sensors (Kolesar and Dyson, 1995;Reston and Kolesar, 1990).…”
