1. A transmitter unit comprising:
a transmitter coil configured to inductively transfer electrical energy to a receiver unit disposed in a living body;
a temperature sensor configured to determine an increase in local temperature of the living 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 living body,
wherein the control device stores a temperature determination routine configured to determine a local temperature at a surface of the living body based at least in part on temperature measurement signals of the temperature sensor and accounting for warming of the temperature sensor caused by the transmitter coil.
