Fraunhofer Institute for Electronic Nano SystemsThe WiTech technology enables wireless energy and data transmission. With this technology surfaces of furniture or interior of automobiles and aeroplanes can supply power and data to every equipment like notebooks, monitors, cell phones or lamps indepentend of their position on the desk top.
To let this vision become reality, the department ASE develops the base of this innovative technology together with a consortium of industrial companies within the scope of the project SUPA (Smart Universal Power Antenna) promoted by the Federal Ministry of Economy and Technology (BMWi).
SUPA is the wireless infrastructure of the future for the data transfer and energy supply of mobile devices. The inductive power supply system consists of a transmitter and a receiver unit. The transmitter unit is invisibly integrated inside or below surfaces and transfers the power, as well as the data to the compatible user device (e.g. a smart phone or a notebook). The challenge of this development is it, to realize that really the complete furniture surface can be used for the power transfer and that a maximum power up 50 W can be supplied to each single device. Due to the effect that the power antenna serves also as data antenna.
Due to the effect that the power antenna serves also as data antenna, various can be wirelessly connected by this technology. Besides, the working range for data and energy transference is consciously minimized (approx. 5 cm to 10 cm). This leads to a low radiation level and optimizes safety of interception of the data networks.
