Introduction to the research group: Our group was found in 1981, under the proposal of Prof. Sessler of TU Darmstadt, Germany. In 1990, the group was named Electrets and Functional Dielectric Group. After more than 30 years of hard work, our group has become the backbone of electret material research and its applications in China, and is one of the most influential research groups in the world for electret research. The research work of the group is now leaded by Prof. Xiaoqing Zhang. Our group has a complete set of test system on the fundamental and application research of electret, piezoelectret and other functional dielectrics, including the corona charging system, measurement system for charge density, surface potential, and charge distribution of electret materials, preparation and modification laboratory of electret materials, thermal stimulated discharging test system, measurement system for quasi-static and dynamic piezoelectric d33 coefficient, high precision impedance analyzer, Radiant Precision Workstation Materials Analyzer, vibration-based energy harvesting test system, and acoustic test system, etc.

Research fields: green micro-energy harvesting, flexible wearable film-transducer, acoustic-electric transducer, air coupled ultrasonic emitter and receiver.

Candidates requirements: below or at 35 years old, have received doctorate, have research experience in domestic and international famous university or research institute, have acquired some research achievement in the field of electret.

Post treatment: 200,000 ¥ pre-tax, housing allowance 2,500 ¥ per month, can rent a postdoctoral apartment.

Application material: detailed personal resume, 3-5 representative papers and two recommendation letters from experts.
