Jacob (Koby) Scheuer, a researcher at the Tel Aviv University (TAU) of Electrical Engineering, Israel, has designed a nano- gyroscope. An optic-fiber nano-sensor had been designed four years earlier, together with an optic gyroscope that operates in combination with the sensor. The system could be used in surgical applications, communications, or virtual reality.
Scheur stated that they have discovered a method to determine rotation in a nano-scale device with the help of the optic sensor. Optic gyroscopes emanate light while rotating, and change their wavelength when the rotation speed is altered, helping determine velocity and position by the variations in light. The nanoscale gyroscope could be deployed in cell phones or watches considering its small size. It also does not require satellite connections like the Global Positioning System.
Scheuer says the combined system comprising the gyroscope and sensor have a wide range of applications. It could be used as a pill that is swallowed and moved through the body and could be used to release drugs in a particular targeted area. It could also enable a doctor perform a surgery on a patient miles away. The system can also navigate independently. The nanogyroscope and sensor has been proved theoretically but it may take several years to be actually implemented. The optic sensor could be applied in security solutions such as information security platforms to protect online information.
