Abstract
A physiological sensor includes an emitter configured to transmit light and a detector configured to receive the transmitted light. The sensor also includes a first accelerometer disposed on a first portion of the sensor and a second accelerometer disposed on a second portion of the sensor, the second portion opposing the first portion. The first and second accelerometers are configured to measure a change in motion that corresponds to a change in distance between the detector and the emitter.
