1. A system for measuring physiological signals, comprising:

  • (a) a patch-ASIC chip adapted for incorporation into a physiological signal monitoring patch comprising a sensor interface, a processor coupled to the sensor interface, a memory element coupled to the processor, a radio comprising an ultra wideband (UWB) transmitter and a narrowband receiver coupled to the memory element that transmits sensor data via the UWB transmitter to a base-ASIC chip and/or a gate-ASIC chip and receives instructions from the base-ASIC chip and/or gate-ASIC chip via the narrowband receiver, and power management circuits that coordinate power on the patch-ASIC chip;

    (b) the gate-ASIC chip comprising a processor that processes sensor data, a memory element coupled to the processor, a radio transceiver coupled to the processor that directs communication between the patch-ASIC chip and the base-ASIC chip, and power management circuits that coordinate power on the gate-ASIC chip; and

    (c) the base-ASIC chip comprising a processor that processes sensor data, a memory element coupled to the processor, a radio comprising a UWB receiver and a narrowband transmitter coupled to the memory element that transmits said instructions to the patch-ASIC chip and/or the gate-ASIC chip via the narrowband transmitter and receives said sensor data from said patch-ASIC chip and/or said gate-ASIC chip via the UWB receiver, power management circuits that coordinate power on the base-ASIC chip, and a host interface through which the base-ASIC chip communicates with a host device,wherein the base-ASIC chip is programmed to use more processing resources than the patch-ASIC chip.
