Respiratory parameters are important indicators of respiratory diseases. These include respiratory rate (RR), inhalation time (Tin), exhalation time (Tex) and their ratio (IER=Tin/Tex). However, most breathing sensors can only detect RR, while suffering from issues of inconvenience and discomfort. Based on a piezo-triboelectric hybrid nanogenerator with nanofibrous membranes, which can convert the biomechanical energy from the breathing process to voltage output signals, our smart, self-powered mask is able to monitor the full spectrum of respiratory indices (RR, Tin, Tex, IER).
