Force sensor and corresponding force monitoring mattress
First Claim
1. A force sensor comprising:
- a first surface and a second surface located opposite the first surface, the first surface is translatable against a resilient force in a direction towards and/or from the second surface;
a distance sensor, arranged to measure the distance between the first surface and the second surface;
characterized in that the force sensor comprises a flexible coupling extending along the direction, flexibly coupling the first surface to the second surface; and
in that the flexible coupling is provided with a resilient means to provide the resilient force; and
a space encompassed by the flexible coupling together with the first surface and the second surface being accessible to the distance sensor, the space filled with a medium for providing the resilient force.
