METHOD OF INCREASING SENSITIVITY USING UNEVENNESS FRAME MATERIAL IN PIEZO FILM SENSOR FOR BIO-SIGNAL MEASUREMENT

摘要

PURPOSE: A method of increasing sensitivity using unevenness frame material in piezo film sensor for bio-signal measurement is provided to supply sufficient pressure required for measuring a signal by applying pressure to only a sensor unit. CONSTITUTION: A piezo film sensor measures bio-information and generates a signal. A sensor unit having a protrusion structure applies more pressure to a measurement area. A foreign material is inserted into the sensor unit to form a protrusion structure on the sensor unit. A silicon pad layer protects the piezo film sensor. Outer case layers(11,15) block impact applied to outside firstly.
