The aim of the present work was to evaluate the possibility of using zinc-air batteries in intraoral medical devices. We analyzed the electrical behavior of zinc-air batteries when submitted to different levels of temperature, humidity, and limited quantities of air. The experimental setup was divided in three different parts. Firstly, a set of batteries were tested within a climatic chamber and subjected to discharging tests similar to those recommended by the manufacturer. The climatic chamber allowed an accurate variation of humidity and temperature. Secondly, the batteries were placed in a small prototype of intraoral medical device and tested in the absence of air. Lastly, we used a robot arm to repeatedly immerse the prototype in artificial saliva. The results obtained demonstrated the viability of zinc-air batteries as a power solution for intraoral medical devices, as they tolerate high levels of humidity and are capable of working with limited quantities of air. In addition, this kind of battery presents a volume to electrical capacity ratio more than three times higher than lithium batteries, which may open important improvement for powered medical devices.

A36 Steel

Tin oxide (SnO2) nanoparticles were successfully added to silicon oxide (SiO2) coatings deposited on A36 steel by the sol-gel and dip-coating methods. These coatings were developed to improve the performance of corrosion protection of steel in a 3 wt % NaCl solution. The effects of modifying the SnO2 particle concentration from 0–7.5 vol % were investigated by polarization resistance, Tafel linear polarization, and electrochemical impedance spectroscopy (EIS). The formation of protective barriers and their corrosion inhibition abilities were demonstrated. It was found by electrochemical studies that all of the coated samples presented higher corrosion resistances compared with an uncoated sample, indicating a generally beneficial effect from the incorporation of the nanoparticles. Furthermore, it was established that the relationship between the SnO2 content and the corrosion inhibition had parabolic behaviour, with an optimum SnO2 concentration of 2.5 vol %. EIS showed that the modified coatings improved barrier properties. The resistance for all of the samples was increased compared with the bare steel. The corrosion rate measurements highlighted the corrosion inhibition effect of SnO2 nanoparticles, and the Tafel polarization curves demonstrated a decrease in system dissolution reactions at the optimal nanoparticle concentration.
