Solar panel power generation human body induction light

Can subdermal solar cells power medical electronic implants?

Recently, subdermal solar cells that can generate electricity by absorbing light transmitted through skin have been proposed as a sustainable electricity source to power medical electronic implants in bodies. However, the results to date have been obtained with animal models.

How does internal body heat affect solar energy harvesting?

Second, internal body heat reduces the efficiency of PV cells. Third, people typically spend more time indoors, which means that these devices will rely on indoor light for energy harvesting purposes. Thus, the amount of harvestable energy is severely compromised.

How much power does an implantable solar cell array generate?

In this paper, we present electrical performance results (up to 9.05 mW/cm) of the implantable solar cell array under 59 human skin samples isolated from 10 cadavers. The results indicate that the power densities depend on the thickness and tone of the human skin, e.g., higher power was generated under thinner and brighter skin.

How much electrical power is generated under the human skin?

The amount of electrical power generated under the human skin depends on the thickness and tone of the skin.

Can solar cells be applied to human skin?

To apply the technology to human beings, electrical performance should be characterized using human skin covering the subdermal solar cells. In this paper, we present electrical performance results (up to 9.05 mW/cm) of the implantable solar cell array under 59 human skin samples isolated from 10 cadavers.

Can human skin samples predict the electrical performance of implanted solar microcell arrays?

Further studies with greater numbers of fresh human skin samples can help statistically estimate the electrical performance of implanted solar microcell arrays with respect to race, age, gender and other factors.
