The Effect of Misalignment of Induction Coils on Tissue Heating during Wireless Transcutaneous Energy Transfer

The effect of induction coil misalignment on the heating of surrounding biological tissues was studied for a wireless inductive powering system with 500 mW output power. It was shown that a lateral misalignment of 2-20 mm can cause an increase in the tissue temperature up to 0.4°C compared with the...

Zusammenfassung:The effect of induction coil misalignment on the heating of surrounding biological tissues was studied for a wireless inductive powering system with 500 mW output power. It was shown that a lateral misalignment of 2-20 mm can cause an increase in the tissue temperature up to 0.4°C compared with the case of coaxial positioning of the coils. Changes in temperature can be caused by a change in power losses in the elements of the system, as well as by displacement of these elements and the mutual influence of their thermal fields.
