A lentil-like sensor that can measure oxygen at physical depths
We’ve been using magnetic resonance imaging before, but it’s only a matter of a few centimeters deep to see the oxygen there. But now the new sensor can be used to explore the depths of the body.
Scientists at the University of California, Berkeley have developed a wireless sensor similar to the herbal insect, dubbed the ‘nerve dust’ It notes nerve signals and muscle performance in real time. It notices the fluctuations in the electrical activity of the muscles and sends the information in the form of ultrasound to a device outside the body. In addition, it can be very helpful in understanding muscle pain and epilepsy very quickly.
It is four and a half millimeters long and only three millimeters wide, which is glued to a thin layer that measures oxygen. The system also includes a microscopic LED and an optical filter that notes the amount of oxygen in the surrounding tissues.
