| Outline of Final Research Achievements |
We developed element technologies ((1) distance sensing to adjacent nodes, (2) wireless communication, (3) node localization, (4) wireless power supply) for tangible user interface called iClay that embeds a number of mm-cubic wirelessly power-supplied sensor nodes with wireless communication capability into clay, as one of applications of small volume computing. Integrating the developed element technologies, we developed a tiny sensor node that integrates wireless power supply, wireless communication and distance sensing, and verified the functionalities by measuring the developed prototype. We are now developing iClay system integration.
