Tactile feedback in robotic and prosthetic applications requires high resolution sensing with short response times, high sensitivity and conformability. Nanoparticle films offer the opportunity to realise high resolution sensors on flexible substrates through ink-jet printing and the ability to tailor devices characteristics to achieve sensitive and rapid transduction. This paper presents modelled and experimental characteristics of a novel nanoparticle resistive based sensor over the range of
