Small, foam hearable captures heart data

In a small study, Danilo Mandic from Imperial College London has shown that his hearable can be used to capture heart data. The device detected heart pulse by sensing the dilation and constriction of tiny blood vessels in the ear canal, using the mechanical part of the electro-mechanical sensor. The hearable is made of foam and molds to the shape of the ear. The goal is a comfortable and discreet continuous monitor that will enable physicians to receive extensive data. In addition to the device’s mechanical sensors, Mandic, a signal processing experter, claims that electrical sensors detect brain activity that could  monitor sleep, epilepsy, and drug delivery, and be used in personal authentication and cyber security.
