Wearable Health Devices are proving to be extremely helpful for people to keep a check on their health conditions. People can monitor their status at a fitness level and also at the proper medical level. With already a number of smart products in the market and the surge in the implementation IoT and AI in the healthcare sector, it is safe to say that the future lies in virtual healthcare and Wearable Health Devices.

In this work, in order to create electrode materials for electrochemical energy converters, composites on porous silicon modified by palladium have been obtained. The functional characteristics of the electrodes have been studied by scanning electron microscopy, X-ray phase analysis, ex-situ and in-situ cyclic voltammetry. The electrode materials based on porous silicon had demonstrated high catalytic activity and specific characteristics in fuel cells with direct oxidation of formic acid. The fuel cell prototype with low palladium content showed the maximum specific power of about 30 mW/cm2 at a current density of 95-100 mA/cm2. © VBRI Press.
