Summary: The research compared penetration depths of different laser frequencies in beef and chicken tissue samples, showing that 808 nm CW laser penetrates significantly deeper than 405 nm CW laser. Additionally, increasing the pulse frequency of the 808 nm PW laser resulted in even higher penetration depths. The study suggests that integrating SHG in PDT with pulsed NIR light could potentially allow for the treatment of larger tumors compared to traditional PDT using blue light.

Summary: During the last decade, biomedical devices have become increasingly powerful and versatile, with subcutaneous devices being one of the most invasive and innovative applications. Managing the battery of subcutaneous devices presents a significant challenge as they can only be handled through surgery, making wireless charging the only feasible option. However, unlike consumer devices, the energy delivered to subcutaneous systems necessarily goes through the human body and tissues, requiring the maximization of energy delivery while ensuring human safety. This article proposes a novel architecture for low-power wireless charging using a Wiegand sensor as a transducer, fulfilling both electrical and medical requirements within an ultralow-power IC prototype.
