Does a multichannel reflective PPG earpiece sensor accurately detect heart rate during rest and exercise?
A novel earpiece PPG sensor with passive motion cancellation can reliably detect heart rate during rest and moderate exercise, offering a low-power and easy-to-wear alternative to conventional earlobe devices.
Wang et al. (2007) studied Heart rate detection. Multichannel reflective PPG earpiece sensor with passive motion cancellation vs. Finger-based approach / conventional earlobe PPG devices was evaluated on Integrity of PPG signal and accuracy of heart rate detection. A novel multichannel reflective PPG earpiece sensor with passive motion cancellation reliably detected heart rate during both rest and moderate exercise.
