Self-powered pressure sensors are needed in applications such as human-machine interaction. This video shows a triboelectric nanogenerator (TENG) based self-powered flexible pressure sensor capable of operating over a wide-range of pressures (3.2 - 1176 kPa). The sensor exhibits excellent sensitivities in various regions of the pressure range, i.e., 3.16, 0.023 and 0.031 V/kPa in the low (1-10 kPa), medium-high (10-500 kPa) and ultra-high (more than 500 kPa) pressure regimes respectively. Stable and repeatable TENG responses are achieved for all three pressure regimes. This is due to the way the real contact area at the TENG interface varies with contact pressure. The broad operating range of devices shown in the video highlight their wide use in applications such as: detecting pressure in wearable devices, human-machine interface, biomedical and automotive applications.
