In this work, a 4-step method of developing flexible, stretchable, and thin graphene-on-polydimethylsiloxane (PDMS) piezoresistive strain sensors is presented. The proposed sensor utilizes the piezoresistive property observed in a dense graphenenanoflakes percolation network sandwiched between two flexible PDMS layers for strain sensing applications. A gait monitoring system comprising of two identical sensors integrated on the knee region of a sports leggings is developed and demonstrated for realtime human motion monitoring.
