Thermal Energy Harvesting: MSX Technology and Micropelt GmbH


Most domestic appliances carry an energy label indicating their efficiency in using electrical energy. Hobs for electric or gas based cooking do not receive such labels because their efficiency was found not to vary much across the market. New technologies for energy-saving cooking are expected to be part of a new EU directive, introducing an energy label for all hobs, because they are considered a major energy savings potential.


MSX Technology´s multisensory cooking technology has proven an energy reduction for cooking of 50% or more, confirmed by the Swiss Federal Laboratories (EMPA) and VDE, the German Association for Electrical, Electronic & Information Technologies.


Energy efficient cooking is based on controlling the cooking process:  A wireless sensor is embedded in the lid of a cooking vessel, transmitting temperature and acoustic data to the hob, which controls the cooking process for best result at minimal energy consumption, according to the respective type of food. The user just pushes a button to start the fully automated cooking process.


A major inhibitor to this technology so far was the energy supply for the sensor. Battery compartments are bulky and hardly remain dish-washer proof over many years and battery replacements. Micropelt's thermal energy harvesting technology allows for a fully embedded and sealed cooking sensor for the life time of the gear. A single 6 mm² Micropelt thermogenerator powers a fully self-sustaining MSX cooking sensor just from the normal process heat.

"This innovative approach results in energy efficient cooking by using a fully embedded (i.e., dishwasher safe), self-powered and wireless sensor to automate the cooking process. A cool combination of an advance in a "domestic" technology with energy conservation. A great application with several benefits."
