1. A telemetered characteristic monitor system for monitoring a characteristic of a user, the system comprising:

  • a sensor for producing a signal indicative of the glucose level in the body of a user; and

    a transmitter device including;

    a housing;

    a sensor interface on a first semiconductor chip within the housing coupled to the sensor to provide an interface between the sensor and the transmitter device;

    processing electronics on a second semiconductor chip within the housing coupled to the sensor interface to process the signals from the sensor;

    data formatting electronics on a third semiconductor chip within the housing and coupled to the processing electronics for converting the signals processed by the processing electronics into a stream of data having a predetermined format; and

    a transmitter coupled to the data formatting electronics for wirelessly transmitting the stream of data to a remotely located data receiving device that is configured to be worn on the user'"'"'s body and includes a tactile indicator for providing to the user at least one of a reminder and an indication of a condition of said characteristic monitor system, said characteristic monitor system being calibrated by inputting a calibrating glucose reading into said remotely located data receiving device.
