A piezopotential-powered active matrix strain sensor array based on a piezopotential-gated graphene transistor (GT) is demonstrated using a piezoelectric polymer. The strain sensor based on the piezopotential-gated GT exhibits excellent performance, including ultrahigh sensitivity (gauge factor = 389) and good durability (>3000 bending and releasing cycles) with a minimum detectable strain at 0.008%.
