Abstract
The present invention broadly provides an improved ingestible capsule (28) that is arranged to sense one or more physiological parameters within a mammalian body, an to transmit such parameters to an extra-corporeal receiver (50). In use, the capsule and receiver perform the method of determining the real-time location of the capsule within a tract of a mammal. This method includes the steps of providing the capsule, the capsule having one or more sensors, ingesting the capsule, transmitting a signal from the capsule, receiving the transmitted signal, and determining the real-time location of the capsule within the tract as a function of the received signal. The received signal may also indicate the value of one or more sensed parameters.
