Hackaday Europe 2026: Playstation 4 to Psychometer

There are many ways to detect stress in an individual. You can use self-reporting checklists, you could try and measure various vital signs like respiratory rate and pulse and infer …. Europe 2026: Playstation 4 to Psychometer.

Or… you could pull some parts out of a Playstation 4, and get hacking. Edwin Hwu did precisely that, creating a device that can image the skin down to the nanometer and potentially even determine fine details about an individual’s health status. He came to Europe 2026 to tell us all about it.

Look Closely Edwin’s background is very relevant to this project. He worked in a research institute in Taiwan where he collaborated with the German National Metrology Institute, working on atomic resolution imaging on silicon wafers. When you’re doing sub-nanometer calibration work for the semiconductor industry, that’s serious stuff, as is the X-ray microscopy that Edwin has dived into.
