Zusammenfassung:PCT No. PCT/CA96/00759 Sec. 371 Date Apr. 30, 1998 Sec. 102(e) Date Apr. 30, 1998 PCT Filed Nov. 18, 1996 PCT Pub. No. WO97/18446 PCT Pub. Date May 22, 1997A capacitance transducer is provided herein for use in measuring loads. It includes a flexible first electrode, a flexible thin film solid dielectric and a fluid dielectric therebetween. A load which is applied to the transducer presses the first electrode, and the thin film dielectric against the second electrode, thereby squeezing out the fluid dielectric to increase the area of the electrodes that are in close proximity. This provides a capacitance transducer that has a significant linear response and an insignificant non-linear response.
