Resonant Proximity Connector for Two-Dimensional Sensor Implantation

In this paper, we propose a stable proximity connector RFC (resonant proximity connector) to TDC (two-dimensional communication) sheet. RFC is an electrode whose length is a quarter of the electromagnetic wavelength. The induced resonance around the electrode reduces the impedance between the connector and TDC sheet, which allows sensor chips to communicate with TDC sheet stably. Since the resonance depends on only the length of the electrode, this connector realizes stable connection of the sensor chip to TDC sheet for the variable gap distance between them. Using this technology, we can construct high density sensor networks on surfaces of clothes, desks, vehicles, and rooms without complicated wiring. The communication sheet can be made of flexible materials like fabric or rubber. We demonstrate the principle of RFC and simulation and experimental results
