“…Optical power transfer (OPT) is one of the least studied techniques to transfer power wirelessly to a biomedical implant [19,39]. Examples of OPT are rare [213][214][215][216] in the literature, even for other applications [213][214][215][216]. Figure 51 shows the complete OPT system where an external TX unit is used to power the implant utilizing an external laser.…”

Wireless power transfer (WPT) systems have become increasingly suitable solutions for the electrical powering of advanced multifunctional micro-electronic devices such as those found in current biomedical implants. The design and implementation of high power transfer efficiency WPT systems are, however, challenging. The size of the WPT system, the separation distance between the outside environment and location of the implanted medical device inside the body, the operating frequency and tissue safety due to power dissipation are key parameters to consider in the design of WPT systems. This article provides a systematic review of the wide range of WPT systems that have been investigated over the last two decades to improve overall system performance. The various strategies implemented to transfer wireless power in implantable medical devices (IMDs) were reviewed, which includes capacitive coupling, inductive coupling, magnetic resonance coupling and, more recently, acoustic and optical powering methods. The strengths and limitations of all these techniques are benchmarked against each other and particular emphasis is placed on comparing the implanted receiver size, the WPT distance, power transfer efficiency and tissue safety presented by the resulting systems. Necessary improvements and trends of each WPT techniques are also indicated per specific IMD.

“…Although OWPT is less efficient over short distances than other technologies, it is expected to be more efficient over long distances. So far, there have been many studies on OWPT [90,[98][99][100][101][102]. Most of them are based on a laser emitter and a solar cell receiver, while some OWPT uses a LED transmitter that has been proven [98,99].…”

“…Optical power transmission (OPT) is one of the least studied technologies for wireless transmission of power to biomedical implants [107][108][109][110][111]. In the literature, there are few examples of OPT, even in other applications [88,90,101,112]. An external T X unit in a complete OPT system uses an external laser to power the implant.…”
