MIT researchers have improved a gel technology that can image microscopic features without expensive equipment, opening up applications in forensics, medicine, and other fields.
Developed by Edward Adelson, Micah Johnson, and colleagues, GelSight acquires surface textures and shapes by pressing a block of clear rubber onto them, revealing striking 3D details. It can even visualize a pulse when pressed on a wrist.
Originally presented in 2009, the technology has been improved to resolve features as small as 2 microns across and is being presented in a paper (PDF) at this week’s Siggraph 2011 computer graphics conference in Vancouver, British Columbia.
When an object is pressed against the clear rubber, its reflective skin on one side distorts to assume the shape of the object. The skin is coated with paint that contains flecks of metal that are smaller than the features they resolve.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
