Design Printable Pressure Sensor Based on 3DP Fabrication

Abstract

In this paper, a low cost, printable pressure sensor is presented. The pressure sensor will be used in personal navigation system which was designed based on micro jet fabrication structure. Inkjet printing and line patterning methods have been used to fabricate polymer resistors and field effect transistors on flexible substrates. A prototype sensor was designed, and the models of mechnical structure and ditital fabrication was also given, fabricated and tested with standard experimental measurements. Results verify that the pressure sensitivity can be measured for both requency and minimum power level difference in good perforamance. The dynamic performance of pressure sensor was also tested by inkjet printing on to flexible substrates including paper, with high resolution in just seconds.
