Resistive force sensing device and method with an advanced communication interface
Abstract:
Several methods and a system of a resistive force sensing device and method with an advanced communication interface are disclosed. An exemplary embodiment provides a force measuring device. The force measuring device includes a resistive sensor having a fixed surface and a movable surface. A spring assembly is positioned between the fixed surface and the movable surface. The spring assembly alters in height in response to a force applied perpendicular to the movable surface and causes a change in a resistance of the resistive sensor. A circuit generates a measurement of the force based on an algorithm that considers a change in the resistance of the resistive sensor. A universal serial bus (USB) interface of the circuit provides digital output of the measurement to a computing device.
