May improve wearable PPG sensors in research; leaves open human validation before clinical consideration.
A novel technique using a single green LED switched between high and low intensities can accurately cancel motion artifacts in wearable photoplethysmographic sensors.
Lee et al. (2016) studied this question. Two reflective pulse signals from a single green LED switched between high and low light intensities was evaluated on Motion artifact cancellation under four different conditions.
