Abstract Optical wireless communication (OWC) has emerged as a promising technology for implantable medical devices because it provides private and secure links patients, low-power consumption, high-speed data transmission. The OWC system’s receiving end typically relies on photodetector with limited field-of-view, necessitating direct line-of-sight connections effective directional nature of light-tissue interaction the in-body can be problematic quality optical signal is rapidly deteriorated due to properties biological tissues, including scattering, absorption, reflection, leading substantial loss beam power reaching photodetector’s sensitive area. In this sense, any misalignment that occurs in device directly impact level further degrade received quality. Numerous studies have been conducted topic free-space environments; nevertheless, only few results found cases. work, we experimentally demonstrate OWC-based system. Three cases were investigated: aligned systems, well lateral angular misalignments. We considered an 810 nm Near-infrared (NIR) LED transmitter mentioned wavelength propagates better than other wavelengths through tissues.

The potential of using light as an alternative energy source and a medium for communicating with medical implants is attractive. Light can propagate through biological tissues, it well known that maximum penetration takes place near-infrared (NIR) light. has several advantages, making quite attractive communication compared to radio frequency (RF) or acoustic waves. communications, in particular, are highly secure, safe, private wireless links while also presenting opportunities low-power implementation. Moreover, the light-based operation free from electromagnetic interference. In context power transfer (WPT) method implants, unique advantages RF acoustics waves, is, secure charging capabilities. emission NIR carrying modulated data passes tissue further be converted into electrical by photovoltaic (PV) cells, enabling powered this chapter, new paradigm modern implanted devices, joint harvesting exploiting light, described. We present progress research (preliminary results) on experiments tissue-mimicking phantom emulating human soft tissue, conducted our laboratory prove concept, showcasing utilizing demonstrate optical channels established at depth approximately 40 mm across phantom, allowing both devices.

The utilization of actual biological tissue (e.g., pork meat samples) and tissue-mimicking phantoms for optical-based in-body data energy transfer studies is crucial. Near-infrared (NIR) light, a part the light spectrum that falls between visible infrared, highly advantageous as carrier transmission due to its superior ability penetrate tissue, instance, human body. Using samples propagation medium prolonged experiments challenging deterioration quality caused by drying in temperature chamber. Typically, controlled-temperature chamber can be utilized warm 37 °C. Some need carried out over long periods, some cases exceeding one hour, including demonstration transmitting large-size high-definition images or videos) real-time through using NIR LED. Moreover, statistical analysis, repeated, therefore degradation sample should avoided. Furthermore, may also encompass investigations into optical wireless power (OWPT) conducted on tissues under illumination employing harvester-based commercial photovoltaic cells (PV) at receiving ends, which would require time charge storage battery supercapacitor) fully. such an experiment not straightforward, requiring careful consideration, standardization issues.
