Thermulab A high-temperature sensor system for greater energy efficiency in gas-fired power stations and combustion engines Microchip with an operating temperature of up to 150°C, developed by IMMS as part of the “Thermulab” project. Photograph: IMMS. Why is it needed? 30 To achieve high thermodynamic efficiency in gas power stations or combustion engines, the working temperatures are raised almost to the thermal limit of the materials contained in the equipment, reaching up to 1200°C, so that highly accurate measurement of the…

S4ECoB Buildings with greater energy efficiency using sound recognition Buildings are responsible for a third of the CO2 emissions and 40% of the total energy consumption in the EU. More than 60% of the energy used there goes into HVAC (heating, ventilation, air conditioning) and lighting.1 As these systems offer the greatest potential for improving the energy balance of buildings, they are the focus of efforts to conserve energy2 in order to achieve the ambitious “20-20-20” climate goals of the EU member states3 – improving energy efficiency…

EROLEDT OLED driver circuit for energy efficient lighting Instruments used in the IMMS laboratory for the characterisation of the Objectives OLED driver developed at the Institute. The ASIC, laid out specifically for the OLED panel, enables it to run efficiently and compensates for the ”Organic LEDs“, or OLEDs*, have been used for some years already in smartphones and television screens. At the moment, they are not in common use for general lighting purposes. An OLED is, however, highly efficient in its use of energy and about 60% more…
