Abstract: In this research work, the development of sensors which are fabricated on the flexible substrates is presented. In particular, we have been focusing on the pressure sensors. Flexible pressure sensors have been intensively developed to be utilized in the health care field, in areas such as artificial skin, human pulse measurement systems, sensors for the detection of bedsores, and sensor sheets for floors. Application of functional organic materials, such as piezoresistive, capacitive or piezoelectric material, to active layers of sensing elements is promising for the development of flexible sensors, where the active layer is sandwiched between two electrodes.
 
In order to enhance the signals from the sensing elements, integration of the elements with organic transistors has been one of the reserch interests. Recently, we have developed the dual-gate organic pressure sensor in which a piezoelectric sensing capacitor was stacked on a low-voltage Organic field-effect transistor. This device was fabricated by means of solution process on a flexible plastic substrate. The detail and potential application of the device will be introduced.
