1. A wearable apparatus for monitoring physiological information for an individual comprising:
- a plurality of electrodes for contacting skin on the individual;
a battery powering at least one of the plurality of electrodes;
a sensor for determining skin conductance across the plurality of electrodes; and
a power control that responds to the sensor wherein the sensor determines that the plurality of electrodes are in contact with the skin based on the skin conductance and wherein the power control powers up circuitry when the plurality of electrodes are in contact with the skin.

Abstract
A biosensor is described which can obtain physiological and accelerometer data from an individual. The biosensor may collect electrodermal activity, accelerometer readings, skin temperature, and other information. Most of the biosensor may be powered off when it is not attached to a person. Based on electrodermal activity the biosensor may automatically turn on when the biosensor comes in contact with an individual. The biosensor may rapidly power up once placed on a person even being fully functional within one second of being attached.
