Abstract: An optically transparent force sensor element compares a force reading from a first strain-sensitive film element with a second strain-sensitive film element, having a compliant and thermally conductive intermediate layer positioned therebetween to compensate for temperature changes. While in the idle state, the optically transparent force sensor can be periodically calibrated to account for additional changes in temperature.

Abstract translation: 光学透明的力传感器元件将来自第一应变敏感膜元件的力读数与第二应变敏感膜元件进行比较，其具有位于其间的柔性导热中间层以补偿温度变化。 在处于空闲状态时，光学透明的力传感器可以周期性地校准以考虑温度的附加变化。
