Porous PDMS force sensitive resistors.

King, M.G. and Baragwanath, A.J. and Rosamond, M.C. and Wood, D. and Gallant, A.J. (2009) 'Porous PDMS force sensitive resistors.', Procedia chemistry., 1 (1). pp. 568-571.


Here we present an elastomeric force sensitive resistor (FSR) made from a porous matrix of polydimethylsiloxane (PDMS) filled with carbon black. The fabrication process is based on the use of a low cost sacrificial sugar cube scaffold which leads to a highly porous and compressible material. By filling this porous matrix with carbon black we can achieve typical resistance changes from 20 kW to 100 W for an applied 95% compressive strain. This material is suitable for a wide variety of sensing applications which include tactile artificial skin for robotics and solvent detection.
