Method and device for transmitting sensor data of an implantable sensor to an external data processing unit

Abstract

During the transmission of sensor data of an implantable sensor with a measurement data recorder, an energy storage unit and a transmitter unit to an external data processing unit with a transmitter/receiver unit, a high-frequency energy carrier signal is firstly emitted from an energy supply unit. At least a part of the energy contained in the high-frequency energy carrier signal is stored in the energy storage unit of the implantable sensor. After the ending of the emission of the high-frequency energy carrier signal, a sensor measurement is carried out using the measurement data recorder of the implantable sensor. The measured sensor data are transmitted from the transmitter unit of the implantable sensor to the transmitter/receiver unit of the external data processing unit. The result is a transmission method, in which interference from the HF feed is avoided, with a compact design.
