Traffic Sign Control by Energy Harvesting Switches
Auerbach. When talking about Energy Harvesting Switches, the first applications that one thinks of are primarily in the smart home, building and industrial automation industry. A ZF Friedrichshafen AG’s customer, Westcotec, has developed an application for traffic signs using the ZF Energy Harvesting Switch.
Westcotec is producing a new traffic warning sign to help horse riders to cross busy rural roads. The riders have Energy Harvesting handheld transmitters and can switch the traffic signs on when approaching the road to warn car drivers of horses crossing. These switches work completely batteryfree and wireless. Only the mechanical actuation of the switch generates enough electrical energy to transmit an RF signal to the traffic sign and activate it. The lights then flash for 60 seconds and can be activated multiple times where groups of horses are crossing the road.
The same idea was implemented to herd animals across a road. When moving the animals the twin amber flashing beacons are triggered by the farmer with a push button on a hand held unit containing the energy harvesting switch.

Energy Harvesting Switches from ZF Detect Status of Windows
With an integrated energy harvesting switch, the window handle can inform of each opening or closing of the window. The mechanical actuation of the RF Switch is created by the change of the window handle status, a small voltage is generated which transmits an RF protocol. This information is used to monitor the status of the window.
