For TDK I have invented and patented a technology allowing Energy and Data transmission through metal, based on NFC technology. It is called Acoustic Data Link (ADL).

The product pre-development according to my concept allows to combine the so-called ADL Communication sub-assembly module (in a miniaturized form factor) with a variety of sensors or actuators, to be able to address a variety of special applications. For demonstration purpose, together with my network, a conventional size demo was built up, allowing to operate an environmental MEMS Sensor (Bosch BME xxx for temperature, humidity, air pressure) through a 4 mm thick steel plate, and to visualize the measured information with a customized Display.

I have also described the technology in a podcast: TDK – POTCASTVIDEO

And there were some press articles that mentions this technology
