Summary description: Advise travellers that the trays used in security check points in the airport have been correctly sterilized and no one has touched them after the process.
Type of activity: Electronic design, mechanical design, firmware development
The customer requires a battery-free system capable of displaying the sanitisation status of an object tray used at airport security checkpoints.
The electronic circuit is powered by an electromagnetic field generated by a transmitter installed inside the sterilizing machine. The power collected is stored in super capacitors, capable of enabling the fuctionalities of the tray. A green led signalling the “cleaness” of the tray and a cpacitor sensor, capable of detecting any touch and swith off the led.
