The potentially blinding disease glaucoma now has a device to track objects virtually. This device invented by scientists is a small computer of size one square mm, implanted in a person’s eyeball. It is a network of units used to track pollution, monitor structural integrity and perform surveillance. The device is powered by an ultra low-power microprocessor, it also has a pressure sensor, memory, a thin film battery, a solar cell and a wireless radio. This new instrument is yet to be launched and the name has still not been finalized. Also, Dennis Sylvester, a professor in the University of Michigan, states that it can be linked to any wireless network of computers as the device’s radio needs no tuning to find the right frequency. The small size of the device makes it economical to manufacture and helps in increasing the semi-conductor industry’s growth. It works every 15 minutes to measure and consumes an average of 5.3 nanowatts. To charge a battery, it needs to be exposed to 10 hours of indoor light each day or 1.5 hours of sunlight and can then store up to a week’s worth of information.
