On the Verge of Artificial Vision

What this episode covers

Philip Troyk, CEO of Sigenics and head of the Pritzker Institute at Illinois Tech, explains the development of a wireless intracortical visual prosthesis designed to restore vision to the blind. The system uses floating microelectrode arrays made of iridium to stimulate the occipital lobe, bypassing damaged eyes and optic nerves to create phosphenes. Troyk details the transition from early wired NIH prototypes to a fully wireless, inductively powered ASIC chip, highlighting the engineering challenges of biocompatibility and signal mapping. The project, funded by the NIH and involving partners like Johns Hopkins and Microprobes, is currently recruiting volunteers for clinical trials to test the interface's ability to convey artificial vision data.

    Ep055: Most Cyberpunk Synthesizer, Data in Your Cells, Bubbly in Your Printer, & Dystopian Peepshow

    Hackaday editors Mike Szczys and Elliot Williams discuss a week of hardware hacks, including a prosthetic hand interface by Berthold Meyer and Coma that converts myoelectric signals to synthesizer control voltages, and a 3D printed split-flap clock by IZ2K using a Raspberry Pi and RTL-SDR. They also cover CNC Kitchen's foaming filaments (Vario Shore TPU and LWPLA) for lightweight aerospace models, and an art project by Caroline Botette using insecure webcams for a 'dystopian peep show.' The episode concludes with commentary on the Mars 2020 rover's drone and DNA-based data storage.

    144. Implantable Chip To Cure Diabetes

    Hosts Daniel and Forbode discuss an MIT team's development of a tiny, implantable device designed to cure type one diabetes by replacing damaged islet cells with living human cells that produce insulin. The device utilizes a proton exchange membrane to extract oxygen from body water vapor, powered by wireless charging via resonant inductive coupling, effectively creating a self-sustaining artificial organ. The hosts analyze the engineering challenges, such as immune rejection and oxygen supply, and speculate on future miniaturization and hybrid power sources using glucose metabolism.

    208. Tiny Antennas for Big Cellular Insights

    The hosts discuss OCEANS, a wireless sensing technology developed by MIT researchers that uses tiny antennas to monitor electrical signals between biological cells. They explain how the system replaces invasive wires with light scattering to detect ion movement, enabling high-definition recording of cellular communication for up to 10 hours. The hosts highlight the potential for this breakthrough to help crack the code behind diseases like arrhythmia and Alzheimer's by understanding how cells interact at a microscopic level.
