Flexible piezoresistive press sensor where CNT nanocomposite is dispersed in PDMS matrix is fabricated using a simple CNT mixing method. The sensor showed resistance sensitivity up to 43.75kPa and maximum of 10% hysteresis. It showed resistance reduction effect after some press stresses that might be related to the squeezing effect of the PDMS matrix. Also it showed resistance drift under constant pressure needing for improvement of mechanical characteristic and supplementing signal processing. ?? 2017 IEEE
