Optical Pulse Ear-Clip

The PPG-to-HR Ear Clip is an alternative way to derive PPG-to-HR from the Shimmer3 GSR.

The Clip is connected to the fleshy part of the earlobe and the Shimmer3 GSR Unit for best quality signal.

The ear lobe optical pulse circuitry includes an on-board amplifier and filter circuit for initial conditioning of the signal. Please contact Shimmer if you require further information. A sample data set for the ear lobe PPG is included in our Consensys software application and can also be found here.
