Battery System for Galvanic Mediated Power to Body Network Devices System and Method
A method for managing power within a network of wearable devices includes galvaniclly transferring a signal between a first device on the network of the wearable devices and a second device on the network of the wearable devices, harvesting the signal at the second device to provide power to the second device, and extracting power management data from the signal.
1 . A method for managing power within a network of wearable devices, the method comprising:
galvanically transferring a signal between a first device on the network of the wearable devices and a second device on the network of the wearable devices;
harvesting the signal at the second device to provide power to the second device; and
extracting power management data from the signal.
2 . The method of claim 1 wherein the power management data comprises a command.
3 . The method of claim 2 wherein the command is a command to change a mode of operation of the second device, wherein in the change in the mode of operation of the second device changes power consumption of the second device.
4 . The method of claim 1 further comprising powering the second device with the power.
5 . The method of claim 1 further comprising charging a battery of the second device with the power.
6 . The method of claim 1 wherein the first device is powered by battery.
7 . A battery system for galvanic mediated power to body network devices, the battery system comprising:
at least one battery cell;
at least one pair of electrodes for galvanic contact with a skin of a user;
power circuitry for sending a power signal through the at least one pair of electrodes to a remote body worn device;
a data transceiver for galvanically communicating data with the remote body worn device.
8 . The battery system of claim 7 further comprising a filter for separating the data from the power signal.
9 . The battery system of claim 8 wherein the data comprises power data.
10 . The battery system of claim 9 wherein the power data comprises messages.
11 . The battery system of claim 10 wherein the messages comprises command messages.
12 . The battery system of claim 11 wherein the command messages include a message to change mode of operation of the remote body worn device, wherein the change in the mode of operation changes power consumption of the remote body worn device.
