NODE INTEGRATION & ENERGY PROJECTSImagine a generic family of autonomous sensor nodes each the size of a sugar lump. Each such "sugar lump" comprises layers of electronics, a radio transceiver, antennas, micro-computer, batteries, solar panels, a multitude of sensors, e.g. constantly sniffing the environment for hazardous chemicals, monitoring pressure, or temperature. Putting so much electronics into such a small volume is a very challenging research task. It requires new technology for vertical interconnection between the individual layers. We have developed a miniature sensor function "layer" illustrated in the pictures. It is only 100 x100 mµ in size and is much smaller than a transistor. We will do a field-demonstration projects on long-lived wireless pressure and presence sensors to be built in roads, rail tracks or bridges. The power supply of very small autonomous systems is a very challenging issue which requires the consideration of several important aspects. These include energy generation from the environment, energy storage and energy management. We will explore a thermoelectric generator connected to a compact battery charging module, built on our patented throughthe- foil thermocouple concept. Contact: |
