The proposed design uses Quantum Dots (QDs) and basic MEMS fabrication techniques to create a flexible thin-film optical heart rate sensor. Fields including health sciences, fitness sciences and psychophysiological studies can benefit from a biosensor that detects heart rate (HR) in a noninvasive manner. Optical heart rate sensors achieve this by being able to collect signals simply through contact with the user. While the sensing method itself is nothing new, the nature of the flexible thin-film structure will allow the device to achieve maintained unobtrusive contact with minimal effort.
