A solar cell is a device which transforms the photoelectric effect of photons into electrical energy. However, since the efficiency is 5% or less in many cases, still a lot of researches and reviews are required to use the solar cell as an efficient sustainable energy source. Therefore, the understanding that a solar cell is more useful for various types of sensors than for a sustainable energy source led to the present invention. In particular, ECG is a microelectrode device which filters noises from ECG signals using gel. The present invention enables easy collection of the current characteristics of a living body, uses light using the effect of micro current, and saves costs by using solar cells compared to other types of medical instruments such as CT and MRI. |
