Abstract
The described technology provides a force sensor apparatus. An elastic pad may be disposed between two force sensors with a force applicator extending at least partially into the elastic pad. When a force is applied to a force applicator, the force applicator transmits the force to one or both of the force sensors via the elastic pad. In an implementation, the force sensors may be resistive sensors. Since resistive sensors may experience thermal drift due to changes in environmental temperature conditions, the differential resistance between the two resistive sensors allows a temperature-independent measurement of the applied force.
