1. A sensor system for sensing at least one physiological characteristic, the sensor system comprising:
- an array comprising first and second sensors;
a processor coupled to the array;
said processor configured to acquire data from said first and second sensors;
a transmission unit coupled to the processor;
an external processing unit;
said external processing unit configured to receive the acquired data via the transmission unit; and
programming executable on at least one of said processor and said external processing unit and configured for carrying out steps comprising;
acquiring a data subset of potential data from said first or second sensor according to a sensor policy;
said sensor policy being established according to said physiological characteristic;
transmitting said data subset to the external processing unit; and
reconstructing said data subset to retrieve data not captured from said first and second sensors.

Abstract
A sensor system and method configured to take multiple channels of sensors, and based on context and user behavior reflected in the signals, identifies specified channels for sensing according to a sensing policy. The sensing policy is used to reduce the amount of data sampled, such that it is possible to reconstruct the values of the non sampled sensors efficiently. The sensing policy is influenced by user and system'"'"'s behavior and can be assigned either offline or in real time.
