smart-MEMPHIS partners RISE Acreo AB (Sensors System group) and Chalmers University of Technology (Micro and Nanosystems group) presented their scientific results on energy harvesting design challenges and supercap through peer-reviewed posters at the 17th PowerMEMS conference in Kanazawa, Japan, November 14-17, 2017 (see the titles of the posters below).
PowerMEMS is an annual conference on micro and nanotechnology for power generation and energy conversion. It is largely academically oriented and has a highly international profile with Japan, the US, Germany, France, China, and the UK among the main contributing countries.
Our contributions were well received, forming a part of the effort to understand the behavior of kinetic harvesters and improve their design in terms of e.g. up-conversion, broader frequency sensitivity, non-linearities and energy losses. These, among other related hot topics regarding kinetic harvesting, were also addressed at the conference by several other oral and poster presentations.
Other focus areas of the conference were material development for thermoelectrical harvesters, electrostatic harvesting and electret development, piezo- and ferroelectric harvesters as well as power electronics design.
