Energy harvesting that are able to operate in higher temperature gradients, and that can conduct electricity well without also conducting heat (something that was until recently thought impossible ), will result in increased efficiency. Future work in thermoelectrics could be to convert wasted heat, such as in automobile engine combustion, into electricity. This type of harvesting is based on the changing capacitance of vibration-dependent capacitors. Vibrations separate the plates of a charged variable capacitor, and mechanical energy is converted into electrical energy. Electrostatic energy harvesters need a polarization source to work and to convert mechanical energy from vibrations into electricity. The polarization
Dalian University of Technology the "Double First-Rate", "985 project", "211 project" and the "E9 Group" of China. During the last Chinese disciplines assessment in 2017, disciplines including engineering, natural sciences, management, economics, et al ranks highly among Chinese top universities. DUT's business education institutions are accredited by AACSB, CAMEA and EQUIS, one of eight Universities in China. Previously known as Dalian University, DUT was founded in 1949. In July 1950, the School of Engineering separated from Dalian University and became Dalian Institute of Technology (大连工学院, DIT). Due to the rearrangement of the Ministry of Education to enhance development of education and construction of new
