21. Conjoined piezoelectric harvesters and carbon supercapacitors for powering intelligent wireless sensors
Abstract : To achieve total freedom of location for intelligent wireless sensors (IWS), these need to be autonomous. To achive this today there is a need of broadband piezoelectric energy harvesting and a long-lasting energy. The Harvester need to be able to provide sufficient amount of energy for the intelligent wireless sensor to perform its task. READ MORE

23. The role of Swedish single-family dwellings in the electricity system - The importance and impacts of solar photovoltaics, demand response, and energy storage
Abstract : This thesis investigates the role Swedish single-family dwellings can play in the electricity system. Both through becoming electricity producers through the use of solar photovoltaic (PV) systems, and the possibilities of demand response (DR) and energy storage in combination with this, and through the DR of electric space heating in the dwellings.
