Abstract:

Recently, a long term work of 10 years has been published where we show that neural growth through electrostimulation is possible in a wireless manner, immersing a conducting material in an electrolyte. The original hypothesis we offered was related with the induction of electrochemical effects and dipole, without a wire connection. Such hypothesis needed to be demonstrated. This thesis focusses on new aspects of bipolar wireless electrochemistry not developed before. Bipolar electrochemistry occurs when an induced potential is generated among poles on an immersed conducting material (bipolar electrode) using driving external electrodes.

Without a cable connection on the bipolar electrode, electrochemical reactions may occur at the induced anode and cathode at opposing poles, opening a large number of possibilities in wireless electrochemistry. The creation of opposing poles in the immersed material and the associated electrochemistry cause changes both in the global cell and in the material, which in turn may change the final phases and properties, and induce phenomena like previously observed wireless neural electrostimulation. In this work, redox gradient materials and a significant decrease of resistance of the cell are reported. Also, oscillating patterns , and magnetoionic effects on Cu oxidation and CoN reduction are reported.
