From: Identifying human body states by using a flexible integrated sensor
a Schematic diagram for the flexible sensor. b Relationship of the resistance change rate with the applied force. Inset: the response curve for the minimum force at 3 mN. c Data-fitting curve for the force sensing. d A cycling test comprising 1000 cycles under the overload force at 20 N. Inset: the response curves before and after one thousand cycles. e Temperature response curve for the flexible sensor. Inset: data-fitting curve satisfying the relationship of the impurity scattering mechanism. f Temperature response curves recorded by our flexible sensor during a six heating–cooling cycle test. g Five hours temperature stability test at room temperature of 25 °C.
