Infrared Imager Maps Out Blood Vessels
This infrared imager can be used to easily locate an individual’s blood vessels while monitoring heart rate at the same time, all without touching the person’s skin. The imager detects shortwave infrared light (wavelengths from 1000 to 1400 nanometers), which is right outside of the visible spectrum (400 to 700 nanometers). It works by shining shortwave infrared light on an object or area of interest, and then converting the low energy infrared light that’s reflected back to the device into shorter, higher-energy wavelengths that the human eye can see.
Tiny, Folding Actuators Spark New Ideas for Medical Nanorobots
The world’s smallest self-folding origami bird demonstrates micron-sized shape memory actuators that fold themselves into 3D configurations and allow atomically thin 2D materials with just a quick jolt of voltage. The scientific advancements from this effort can enable smart material design and interaction with the molecular biological world.
Origami-Inspired Medical Patch for Minimally Invasive Surgery
Many surgeries are performed via minimally invasive procedures, in which and miniature cameras and surgical tools are threaded through the body through a small incision is made. Surgeons can face challenges at an important step in the process: the sealing of internal wounds and tears. Engineers have designed a medical patch that can be folded around minimally invasive surgical tools and delivered through airways, intestines, and other narrow spaces, to patch up internal injuries.
Implant Improves Quality of Life for People with Inner Ear Disorder
A multichannel vestibular implant helps patients with BVH by electrically bypassing malfunctioning areas of the inner ear and restoring most of their ability to walk, move, and turn their head without dizziness and orient themselves in space. Researchers modified a cochlear implant to instead activate the nearby vestibular nerve in response to signals from a motion sensor on the patient’s head.
