Abstract
A resilient force sensor unit is disclosed, the force sensor unit has a thin film force sensing element sandwiched between a top substrate and a bottom substrate. A first protective layer is configured on a bottom surface of the bottom substrate, and a second protective layer is configured on a top surface of the top substrate. The protective layer helps prevent potential creases or wrinkles from occurring on the force sensor unit. Complete folding of the sensor device becomes less possible due to the additional thickness/hardness of the stacked material layers, thereby lowering the chance a crease is formed during use.
Claims21
A resilient force sensor unit, comprising:
- a top thin film substrate;
- a bottom thin film substrate;
- a thin film force sensing element sandwiched between the top thin film substrate and the bottom thin film substrate, and
- a bottom protective layer, configured on a bottom surface of the bottom thin film substrate;
- wherein
- the force sensing element has a responsive area, when a force is applied to this area from top or bottom, the force sensing element will output a corresponding responsive signal.
A resilient force sensor unit, comprising:
- a top thin film substrate;
- a bottom thin film substrate;
- a thin film force sensing element sandwiched between the top thin film substrate and the bottom thin film substrate, and
- at least a fixing unit penetrating through the top thin film substrate and the bottom thin film substrate to prevent the two substrates from becoming misaligned.
