PlayStation 4 Blu-ray Head Sparks DIY High-Speed Dermal Microscope

Edwin Hwu demonstrates a High Speed Dermal AFM (HS-DAFM) built from a PS4 Blu-ray optical head to image skin at the nanoscale, enabling rapid dermatological and cosmetic analysis; with machine learning, the setup is explored for diagnosing conditions such as asthma (about 75% accuracy), showing a cost-effective, DIY path beyond traditional lab AFMs.
