 pyroelectric nanogenerators have been developed to convert thermal energy into electrical energy. These generators are capable of generating power from temperature differences as small as 20 degrees Celsius. When combined with a multi-pulse electric field, these generators can produce up to seven times more power than when only one pulse is applied. This technology has potential applications in renewable energy sources such as solar cells or wind turbines.
