Small form factor medical sensor structure and method therefor
First Claim
1. A medical sensor for measuring a parameter comprising:
- a polyimide layer;
a first conductive region overlying the polyimide layer; and
a second conductive region underlying the polyimide layer where the medical sensor is configured such that a change in the parameter produces a change in the polyimide layer.

Abstract
A measurement system for measuring a parameter of the muscular-skeletal system is disclosed. The measurement system comprises a capacitor, a signal generator, a digital counter, counter register, a digital clock, a digital timer, and a data register. The sensor of the measurement system is the capacitor. The measurement system generates a repeating signal having a measurement cycle that corresponds to the capacitance of the capacitor. The capacitor comprises more than one capacitor mechanically in series. Electrically, the capacitor comprises more than one capacitor in parallel. In one embodiment, the capacitor includes a dielectric layer comprising polyimide. A force, pressure, or load is applied to the capacitor that elastically compresses the device.
