Abstract

Multifunctional sensors have attracted great interests as potential candidates for application of human health and ambient circumstance monitoring devices. Recent investigations are focused on novel materials or device structure to achieve simultaneously detecting various stimulations. Here, the photovoltaic-pyroelectric-piezoelectric coupled effect induced electricity for self-powered coupled sensing in ferroelectric BaTiO3 material is reported, which can be utilized to detect light intensity, temperature variation, and vibration frequency with the sensitivities of 0.17 nA (mW cm(-2))(-1), 4.80 nA K-1, 21.02 nA Hz(-1) (<= 17 Hz), respectively. The sensitivities for the light+temperature, temperature+vibration, and light+temperature+vibration monitoring of the device are found to depend on the variation of spontaneous polarization in the BaTiO3 material. This work provides an inspiration to achieve individual/simultaneous light, temperature, and vibration sensing by employing ferroelectric materials, which greatly simplifies the structure of a multifunctional sensor, and holds significant potentials for self-powered sensing in healthcare and ambient environment monitoring fields.
