Thin Film Strain Sensor, Resistors, Material & Evaporation

	Patterned thin film resistors can serve as sensitive strain sensors.

	Nichrome sputtered strain sensor on Liquid Crystal Polymer (LCP) substrate; the traces are 25 um wide. The serpentine configuration increases sensitivity to substrate deformation; the use of a flexible substrate allows conformal mounting.	Excellent linear response of a prototype thin film strain sensor.
