Perforated Paper-Based Piezoresistive Force Sensor

Abstract

15th Conference on Ph.D Research in Microelectronics and Electronics (PRIME) -- JUL 15-18, 2019 -- Lausanne, SWITZERLANDIn this work, a paper-based disposable piezoresistive force sensor has been designed, fabricated and tested along with peripheral electronic circuit. Strathmore (R) 400 series Bristol paper is employed as the substrate and it is coated with graphite and silver ink to form a perforated cantilever beam which constitutes the sensor part of the force sensing system. The proposed force sensing system can measure a force ranging to 24 mN with a force resolution of 196 mu N. The implemented sensor has a sensitivity of 8.63 mV/mN.Dialogue Semiconductor,Cadence,Coilcraft,Melexis,Springer,IEEE,IEEE Circuits & Syst Soc,Ecole Polytechnique Federale Lausanne,ams,Ecole Polytechnique Federale Lausanne, RFIC Grp,Ecole Polytechnique Federale Lausanne, ICLAB LabTUBITAK project [117E236]The authors would like to sincerely thank TUBITAK project no:117E236 and project members Oznur Mete & Berkay Alcicek
