Triaxial forces are estimated from the resistance changes of NiCr thin film strain gauge attached to three microcantilevers. The output voltage of the Wheatstone bridge that comprises a gauge film and three reference resistances is acquired using an A/D converter after amplification. Triaxial forces are calculated from the output voltages of three microcantilevers by simple matrix multiplication. Nonlinearity and crosstalk are less than 4% when the normal force applied is up to 1N and less than 10% when the shear force applied is up to 0.2N. Active touch sensing was demonstrated using an object having a striped profile measuring 0.1mm in height and 1mm in width.本誌: 電気学会論文誌E（センサ・マイクロマシン部門誌） Vol.134 No.3 （2014） 特集：センサ・マイクロマシン英文特集号本誌掲載ページ: 58-63 p原稿種別: 論文／英語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejsmas/134/3/134_58/_article/-char/ja/ Show more
