1. A method for minimizing the effects of motion artifact on sensor readings taken during continuous transdermal monitoring of a body part in motion, the method comprising:

  • monitoring, with a processor, an output signal from an accelerometer, wherein the output signal indicates acceleration and deceleration of the body part of a user as the body part is in motion;

    determining, with the processor, that the output signal is within a predetermined range that includes indication of acceleration and deceleration, wherein indication of acceleration and deceleration corresponds with a motion direction change of the body part in motion;

    based on the determination that the output signal is within the predetermined range, monitoring, with the processor, a plurality of readings from a sensor, wherein monitoring the plurality of readings from the sensor occurs over a time window that coincides with the output signal remaining within the predetermined range; and

    recording in a memory device the monitored plurality of readings from the sensor.
