Just to let you know, Philips has filed a patent application for an electronic drug delivery capsule with remote controlled medication release, and RFID technology for authentication and identification purposes.
The abstract of the patent application:
The pill includes a housing; a medicament reservoir for storing a medicament; an electronically controlled release valve or hatch for dispensing one or more medicaments stored in the medicament reservoir while traversing the gastrointestinal tract; control and timing circuitry for opening and closing the valve; and a battery. The control and timing circuitry opens and closes the valve throughout a dispensing time period in accordance with a preset dispensing timing pattern which is programmed within the control and timing circuitry. RF communication circuitry receives control signals for remotely overriding the preset dispensing timing pattern, reprogramming the control and timing circuitry, or terminating the dispensing of the medicament within the body. The pill includes an RFID tag for tracking, identification, inventory and other purposes.
Patent application: ELECTRONICALLY AND REMOTELY CONTROLLED PILL AND SYSTEM FOR DELIVERING AT LEAST ONE MEDICAMENT
