Hitachi µ-Chip Research Project

The µ-Chip Project was a research cooperation between the Distributed Systems Group (DSG) at ETH Zurich and the Hitachi Systems Development Laboratory (SDL), Japan. The aim of the cooperation was to explore potential µ-chip applications and business cases with focus to ubiquitous computing scenarios. For that, Hitachi provided evaluation kits of the latest µ-chip technology, including documentation and hardware support.

At ETH, we investigated novel concepts and usage scenarios based on the large-scale deployment of RFID technology. As proof of concept, we developed and prototypically implemented demonstrators where appropriate. The µ-Chip Project was officially launched in February 2003 and was completed in February 2005.

Technology: The Hitachi µ-Chip (mu-Chip) is a tiny passive RFID-chip of 0.4 mm x 0.4 mm size with 128-bit read only memory. The µ-Chip equipment operates at a radio frequency of 2.45 GHz with a maximum communication length of up to 25 cm. More detailed technical information can be found at the Hitachi µ-Chip home page.

Together with my former colleague Svetlana Domnitcheva, I was responsible for the management of our collaboration with Hitachi on behalf of the Distributed Systems Group at ETH Zurich.
