Frequency-division-multiplexed signal and power transfer for wearable devices networked via conductive embroideries on a cloth

We propose a powering scheme for tiny wearable devices attached on a cloth without individual one-to-one wires. Devices with a special connector consisting of a tack and a clutch are stuck through a special cloth embroidered with conductive threads. Physical mounting of the devices and electrical connection are integrated into a single action, i.e., just sticking the connector. Combining microwave/high-frequency circuit technology and recent highly conductive soft fabric materials opens up a new implementation scheme for wearable sensing/display/communication systems.
