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 (Rx1, Rx2, Rx3, Rx4, Ry1, Ry2, Ry3, Ry4) arranged on a substantially planar deformable membrane (12, 13, 14) and mounted along two different directions. The resistive gauges (Rx1, Rx2, Rx3, Rx4, Ry1, Ry2, Ry3, Ry4) of each of the Wheastone bridges are respectively arranged on disjointed portions of the membrane (12, 13, 14), and two gauges (Rx2, Rx3; Ry1, Ry4) of at least one Wheastone bridge are placed on a non-deformable zone (13) of the membrane (12, 13, 14).
