Energy harvesting, converting the ambient energy into electrical energy, is emerging as a potential alternative power supply for batteries that are ubiquitous in electronic devices. Materials and approaches for on-body energy harvesting The human body is a challenging platform for energy harvesting. Scientists from China's Dalian Maritime University have now utilized that same motion in an underwater energy-harvesting device. For thermoelectrics, the small temperature differences between the skin and air necessitate materials with low thermal conductivities in order to maintain useful output powers. Most piezoelectric materials for energy harvesting exhibit a well-defined polar axis, and the direction of the applied stress relative to the polar axis would affect the energy harvesting performance. Recently, the triboelectric nanogenerator (TENG) for harvesting low-frequency energy has attracted the attention of academia. CEHMS center members specialize in materials, structural dynamics, electronics and storage covering micro-scale to macro-scale systems. Out of various possible energy harvesting technologies, piezoelectric vibration energy harvesting has emerged as a method of choice for powering meso-to-micro scale devices.
