Abstract
A strain gauge primarily designed for dynamic measurements and requiring very little force to produce a change in length. The strain gauge is alternately concave and convex in shape, such as a sinusoidal curve with nodes of low resistance on the convex portions and strain gauges of high resistance on the concave portions. The gauge is unbonded and can be stretched with very little force. The strain gauge is utilized in an instrument to monitor infant respiration and detect episodes of apnea.
