The influence of washing on the inductive elements of the energy harvester integrated into clothing is under investigation. For the experiment were prepared single-layer and five-layer coils. Coils differ from each other of insulating layers and type of waterproof isolation (lamination, different coatings). After the application of protective coatings and test for water resistance electrical conductivity loss of 15% for one-layer inductive element with coating Nr.1 and loss of 12% for one-layer inductive element with coating Nr.2 was found. After preliminary washing test five-layers inductive element showed electrical conductivity loss of up to 3%. Some inductive element has shown destruction of the structure and coating. The preliminary washing test results showed that the structure of the coils with thermoplastic adhesive coating has not destruction. Also hasn’t destruction coil with lamination. The disadvantage of the present coil with lamination is an increase in linear dimensions and stiffness of coil.
