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
Wuhan University of Technology Automotive Polytechnic University. What was more, in 1999, Hubei No.1 Mechanical Industry School and Hubei Energy Economy School were merged into the university. Later in May 2000, it merged with the other two universities mentioned in the beginning and thus formed Wuhan University of Technology. Currently, the university owns 23 academic schools, 9 state key disciplines, 74 Doctoral programs, 135 Master's programs as well as 82 Bachelor's programs. WUT has about 5,570 staff members, including 650 professors, 3 academicians of China Academy of Engineering and 3 academicians of China Academy of Science. Besides, over 36,000 undergraduates, 16000 postgraduates (including Master
