1. A transmitter unit comprising:
a housing comprising a transmitter coil configured to inductively transfer electrical energy to a receiver unit disposed in a part of a body of a patient in response to a contact made between a contact surface of the housing and the body of the patient, the receiver unit comprising a receiver coil;
a temperature sensor configured to determine an increase in local temperature of the body caused by the inductive transfer of electrical energy to the receiver unit; and
a control device configured to control operation of the transmitter coil based at least in part on the increase in local temperature of the body,
wherein the control device stores a temperature determination routine configured to determine a local temperature at a surface of the body based at least in part on temperature measurement signals of the temperature sensor;
wherein the temperature determination routine is configured to stop the operation of the transmitter coil at a first time point and contains an algorithm configured to calculate the local temperature based at least in part on a decay curve determined based at least in part on the temperature measurement signals from the temperature sensor after the first time point, wherein the temperature determination routine is configured to account for warming of the temperature sensor caused by eddy currents.
