[4] In 1994 and 1996, he was appointed university professor for sensorics and for applied condensed-matter physics of the University of Potsdam. [5] [6]

From 1997 until 2000, Gerhard served as director of the institute of physics and astronomy, from 2006 to 2008 as vice dean, and from 2008 to 2012 as dean of the faculty of science at the university. [7] Between 2004 and 2012, he chaired the joint board of the master-of-science program in polymer science at the four universities with science faculties in Berlin and Potsdam. [8] From 2014 until 2016 he was a member of the university senate in Potsdam. [9] He has undertaken visiting appointments at Bell Laboratories in Murray Hill, NJ, USA (1981, 1982, 1983), at the Tongji University in Shanghai, China (1987 and 1989), at the École Normal Supérieure (ENS) in Cachan, France (1995/96 and 2014/15), at the University of São Paulo (USP) in São Carlos, Brazil (1999, 2005–06, 2012), at the École Supérieure de Physique et de Chimie Industrielles (ESPCI) in Paris, France (1999), at the Hebrew University of Jerusalem, [10] Israel (HUJI) (2013), at the Xi'an Jiaotong University (XJTU) in Xi'an, China (2015, 2017, 2019), and at Chongqing University in Chongqing, China (2018 and 2019). [11]

Gerhard served as secretary of the 5th IEEE International Symposium on Electrets (ISE) in Heidelberg (1985), [12] co-chair of the 7th IEEE International Symposium on Electrets (ISE) in Berlin (1991), [13] chair of the 10th IEEE International Conference on Solid Dielectrics (ICSD) in Potsdam (2010) [14] and chair of the 2nd International Conference on Electromechanically Active Polymers (EuroEAP) in Potsdam (2012). [15] He was the vice president for technical activities of the IEEE Dielectrics and Electrical Insulation Society (DEIS) in 2007–2008 and 2014–2015. [16] From January 2018 through December 2019 he served as president of the IEEE Dielectrics & Electrical Insulation Society (DEIS). [17]

His research portfolio includes polymer electrets with quasi-permanent space charge, ferro- or piezoelectrets (polymer films with electrically charged cavities), ferroelectric polymers with piezo- and pyroelectric properties, polymer composites with novel property combinations, physical mechanisms of dipole orientation and charge storage, electrically deformable dielectric elastomers (sometimes also called "electro-electrets"), as well as the physics of musical instruments.

In electrical engineering, partial discharge (PD) is a localized dielectric breakdown (DB) of a small portion of a solid or fluid electrical insulation (EI) system under high voltage (HV) stress. While a corona discharge (CD) is usually revealed by a relatively steady glow or brush discharge (BD) in air, partial discharges within solid insulation system are not visible.

The Technische Universität Darmstadt, commonly known as TU Darmstadt, is a research university in the city of Darmstadt, Germany. It was founded in 1877 and received the right to award doctorates in 1899. In 1882, it was the first university in the world to set up a chair in electrical engineering. In 1883, the university founded the first faculty of electrical engineering and introduced the world's first degree course in electrical engineering. In 2004, it became the first German university to be declared as an autonomous university. TU Darmstadt has assumed a pioneering role in Germany. Computer science, electrical engineering, artificial intelligence, mechatronics, business informatics, political science and many more courses were introduced as scientific disciplines in Germany by Darmstadt faculty.

Transformer oil or insulating oil is an oil that is stable at high temperatures and has excellent electrical insulating properties. It is used in oil-filled wet transformers, some types of high-voltage capacitors, fluorescent lamp ballasts, and some types of high-voltage switches and circuit breakers. Its functions are to insulate, suppress corona discharge and arcing, and to serve as a coolant.

<span class="mw-page-title-main">Electrical treeing</span>

In electrical engineering, treeing is an electrical pre-breakdown phenomenon in solid insulation. It is a damaging process due to partial discharges and progresses through the stressed dielectric insulation, in a path resembling the branches of a tree. Treeing of solid high-voltage cable insulation is a common breakdown mechanism and source of electrical faults in underground power cables.

A ferroelectret, also known as a piezoelectret, is a thin film of polymer foams, exhibiting piezoelectric and pyroelectric properties after electric charging. Ferroelectret foams usually consist of a cellular polymer structure filled with air. Polymer-air composites are elastically soft due to their high air content as well as due to the size and shape of the polymer walls. Their elastically soft composite structure is one essential key for the working principle of ferroelectrets, besides the permanent trapping of electric charges inside the polymer voids. The elastic properties allow large deformations of the electrically charged voids. However, the composite structure can also possibly limit the stability and consequently the range of applications.

A silicone oil is any liquid polymerized siloxane with organic side chains. The most important member is polydimethylsiloxane. These polymers are of commercial interest because of their relatively high thermal stability and their lubricating properties.
