Abstract Increasing global digitalization brings huge amounts of data. Finding a successful way to handle all this data and to transform it into real insights will be a critical success factor in the future. The biggest challenge for data science applications in marketing is that many marketing people studied marketing because they no longer wanted to do mathematics. A good marketing campaign will still have to be creative, touch emotions and build a brand, but more and more marketing managers will also need technical and analytical skills. It will more than ever be necessary to determine real causal effects to pull the right levers. Consumer insights have always been considered a major driver for growth, but in the digital world, successful growth can also come from improved technical and analytical implementation and skillful application of new tools and methods.

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