“…The flawless wireless communication in 9600bps enables reliable data exchange. Results found in the related area of body-area networks differ, as transmission goes through the body or arm, not just skin [19].…”

“…Sensing body activity directly presents an alternative to using the body as a spatial input canvas, such as sensing muscle tension [37], tongue motions using prototypes worn inside the mouth [21,36] and micro-devices integrated into worn contact lenses [19]. Direct output through the body has been shown with electrodes that stimulate the user's muscles [44] or the user's ear to influence the sense of balance [9].…”

We investigate implanted user interfaces that small devices provide when implanted underneath human skin. Such devices always stay with the user, making their implanted user interfaces available at all times. We discuss four core challenges of implanted user interfaces: how to sense input through the skin, how to produce output, how to communicate amongst one another and with external infrastructure, and how to remain powered. We investigate these four challenges in a technical evaluation where we surgically implant study devices into a specimen arm. We find that traditional interfaces do work through skin. We then demonstrate how to deploy a prototype device on participants, using artificial skin to simulate implantation. We close with a discussion of medical considerations of implanted user interfaces, risks and limitations, and project into the future.

“…Thus many biomarkers that are found in the blood, such as glucose, are also detectable in the tear film. Additionally, with sophisticated optoelectronics and optical manipulation, such as vertical cavity surface emitting lasers (VCSELs) and micro-lens arrays, it may be possible to create on-lens displays [1]. Such a display could be useful as a headsup display for pilots or gamers.…”

The overarching goal of an active contact lens is to integrate sensing or display functionality onto a wearable device, enabling on-lens medical monitoring and heads-up displays. We present progress toward a wirelessly-powered active contact lens comprising a transparent polymer substrate, loop antenna, power harvesting IC, and a custom micro-LED. The fully integrated radio power harvesting and a power management system was fabricated in a 0.13 μm CMOS process and utilizes a small onchip capacitor as an energy storage element to light up a micro-LED pixel. We have demonstrated wireless power transfer and LED intensity control using the custom IC and on-lens antenna.
