Contactless power and information transmission

In some applications, contacts between two devices are the first cause of dysfunctions. The aim of this paper is to transfer contactless power energy to add new functions to a tool (e.g., drill machine). A bidirectional communication is also needed. This is realized with an ironless high-frequency transformer for both power and information transmission. Different coil geometries have been studied to reduce mutual inductance between power and information coils. This new solution enables to build low-cost and smart energy transfer systems including communication.
