A conductive terminal is positioned in an insulative housing to constitute an electrical connector. The floating gate PMOS transistor includes a source that forms a first terminal of the memory cell, a drain and a gate. The organic light emitting display device includes: a frame; a first substrate disposed on the frame, a display unit being formed on a surface of the first substrate; a second substrate disposed so as to face the first substrate; a driver integrated circuit disposed on either the first substrate or the second substrate; and a buffer member formed so as to cover the driver IC. The sensor also includes an electrical circuit coupled to the piezoresistive material that is operable to detect the change in the electrical resistance of the piezoresistive material due to the interfacial tension.
