This tiniest device measures upto one square millimeter, but don’t go on the small size of this computer because pack inside the tiniest device is an ultra low power microprocessor, a pressure sensor , solar cell, wireless radio for communication to an external reader device, memory and a thin film battery.
Remember Gulliver’s travel to Lilliput, maybe our world is also turning smaller day by day because in the future this smallest computer (Unnamed uptill now) can be use efficiently for tracking, surveillance, military purposes and what not?
The miniscule computer system is developed by Professor Dennis Sylvester, David Wentzloff and David Blaauw.
Dennis Sylvester, professor of electrical engineering and computer science at the University of Michigan further explained and said:” This is the very first true millimeter-scale complete computing system; small computing systems are possible by the usage of low-power components that can fit on a chip. A complete millimeter scale computer system enables us to collect, store and transmit data”.
The first application of millimeter scale computing system is in the field of medical. This device is implanted in the human eye to measure eye pressure and track the progress of glaucoma , which is a potential blinding disease.
The system starts working after every 15 minutes to take measurements and uses an average of 5.3 nanowatts energy, battery is charged through 10 hours of indoor light each day or 1.5 hours of sunlight.
The device is equipped with a wireless radio for communicating to external reader device but it can not communicate with computer systems of its own type.
Scientists are now working on decreasing the radio’s power consumption so that it’s compatible with millimeter-scale batteries.
Let’s hope this incredible device will open doors for further advancements in the miniscule computer systems.
