CADwalk GmbH & Co. KG simulate Semiconductor-Devices for highest Frequencies in III-V-Technology and is developing Wireless Sensor Notes WSN since more than fifteen Years. Simulation: We build III-V-Layers in CAD and caluculate in FEM-Simulations e.g. current characteristics. 03.05.2010 2
CADwalk integrates synergetic concepts to create necessary functionality at minimized costs and cost of ownership. With a small microcontroller, a dual-axis MEMS-sensor, a very thin lithium-polymer battery and an ultra flat Bluetooth transceiver we build one of the smallest, most useful, time and cost saving wireless-acceleration-measurement-system for the automation-, semiconductor- and flat-panel-industry. It clearly watches jitter and not allowed touches during a handling sequence. 03.05.2010 3

Energy Harvesting The four main varieties in the litrature are: Thermal energy scavengers using e.g. thermo-electrics Vibrational energy scavengers, usually using electro-magnetic or piezo-electric generators Optical energy scavengers unsing solar cells Radio-frequency energy scavengers using antennae 03.05.2010 21
Polymer Power: Dielectric Elastomers and Their Applications in Distributed Actuation and Power Generation Proceedings of ISSS 2005 International Conference on Smart Materials Structures and Systems July 28-30, 2005, Bangalore, India A heel strike boot generator developed by SRI (Fig. 4) investigated ways to harvest otherwise wasted energy from walking 9. The demonstrated recovered energy on the order of 1 W per boot can be used to supplement battery power charge small devices such as handhelds or cell phones, as an emergency backup source of power, for specialized onboard boot functions such as massaging or, in the future, to enhance walking and other mobility performance. 03.05.2010 22
