Innovative packaging technologies and power aware design enable system shrinking considering automotive requirements. Miniaturized wireless sensors become more and more important. During the design process the coupling of very narrow positioned components and the interdependence of hardware, software, and packaging have to be considered. Today's advances in packaging and manufacturing technology allow the enhancement of the miniaturization level, which enables the integration of reliable self-sufficient sensors into objects like valves. Further power efficiency is needed to achieve long operating lightweight systems. This paper discusses the degrees of freedom in designing miniaturized self-sufficient sensors considering a TPMS (Tire Pressure Monitoring Systems) as an example. Especially tire pressure sensors electronics can be extended to equip a tire with intelligence and to allow vehicle adaptation to weather and road condition. The exemplary requirements on TPMS, the selection of components and interconnection technology as part of design flow to achieve miniaturized wireless sensors will be introduced. Different design options are traded off to meet demands. Finally prototypes of network capable wireless sensors as well as sensor modules for a direct TPMS were presented.
