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 born China, several departments, including Electrical Engineering, Physics and Law, were transferred to other universities and institutions. Meanwhile, scholars from other universities came to enlarge the departments of Chemical Engineering, Mechanical Engineering. The university started to expand right after the rearrangement, attracting more scholars and funding. To ensure future growth, the then-headmaster, Bochuan Qu, strategically moved the university's main campus to the bay area of suburban Dalian. In October 1960, DIT became one of the 26 key national universities directly under the State Ministry of Education. Graduate School of DIT was established in April 1986. In March 1988, DIT changed
