3.2.1.1 Current Consumption and Life Span

For initial current consumption tests, the power pads on the wireless patch were connected to a power analyzer capable of measuring currents in the nA range. The average current numbers collected were used to estimate the expected life span of the device under battery power. For practical testing of life span, the patch was enabled and left running in auto-advertisement mode. Temperature data was still available more than 4 days from initial start-up of the patch.
