System, devices, and method for on-body data and power transmission
First Claim
1. A method of synchronizing nodes within an on-body sensor network, the method comprising:
- transmitting, by a master hub located on a surface of a user, an initialization electrical current pulse into the surface;
receiving, by at least one sensor node located on the surface, the initialization electrical current pulse from the surface;
transmitting, by the at least one sensor node, an acknowledge electrical current pulse into the surface after a pre-determined delay and in response to receipt of the initialization electrical current pulse;
detecting, by the master hub, the acknowledge electrical current pulse;
transmitting, by the master hub, a triggering electrical current pulse into the surface, the triggering electrical current pulse including electrical power and data; and
receiving, by the at least one sensor node, the triggering electrical current pulse from the surface, the electrical power and data triggering the at least one sensor node to begin generating sensor information.

Abstract
An on-body sensor system includes a hub configured to be attached to a surface of a user. The hub being further configured to transmit electrical power and/or data signals into the surface and to receive response data signals from the surface. The system further including at least one sensor node configured to be attached to the surface. The sensor node being further configured to receive the electrical power and data signals from the hub through the surface and to transmit the response data signals into the surface. The electrical power from the hub can power the sensor node and cause or enable the at least one sensor node to generate sensor information that is transmitted back to the hub within the response data signals.
