DEVICE FOR MEASURING FORCE BY RESISTIVE DETECTION WITH DOUBLE WHEASTONE BRIDGE

摘要

The invention concerns a device for measuring force by resistive detection with double Wheastone bridge comprising at least eight resistive gauges (R_x1, R_x2, R_x3, R_x4, R_y1, R_y2, R_y3, R_y4) arranged on a substantially planar deformable membrane (12, 13, 14) and mounted along two different directions. The resistive gauges (R_x1, R_x2, R_x3, R_x4, R_y1, R_y2, R_y3, R_y4) of each of the Wheastone bridges are respectively arranged on disjointed portions of the membrane (12, 13, 14), and two gauges (R_x2, R_x3; R_y1, R_y4) of at least one Wheastone bridge are placed on a non-deformable zone (13) of the membrane (12, 13, 14).
