Researchers at Michigan University Develop World Tiniest Computer, Smaller than a Grain of Rice
Engineers at the University of Michigan have come out with World Tiniest Computer in the world. A device which is 0.3 mm x 0.3 mm in size could help find new ways to monitor and treat cancer, completely dwarfed by a grain of rice.
In the world of tiny computing, Michigan scientists on Thursday just outdid IBM by developing a computer that could stand on the tip of a grain of rice. The worlds tiniest computer consists of a processor, RAM, Photovoltaics, system memory, and wireless transmitters and receivers in place of conventional radio antennas to make the system communication ready.
Since they are minuscule in size to have conventional radio antennae, the system relies on light to transmit and receive data and is powered by a base station which provides light and programming data, and it receives the data. The minuscule device drew a comparison with IBM’s own 1mm x 1mm (smaller than a grain of salt) computer which was developed in March this year.
“The creation is about more than just size and we are not sure whether the device should be called computers or not because of its limited functionality required. We are about 10 times smaller so we can fit anywhere even in smaller spaces,” said David Blaauw, a professor at the US University of Michigan co-leading the project, said in an email statement.
To make a breakthrough in terms of technology, U-M engineer had to invent new ways of approaching circuit design that would be equally low-power but could also tolerate light. Being flexible and reimagined for a variety of purposes, these microdevices erase all prior programming and data as soon as they lose power.
Designed as a precision temperature sensor, the new device currently serves as a temperature sensor in tumors as it uses electronic pulses to convert temperatures into timed intervals. According to the researchers, the tiny computer can open doors in other fields also. Uses of this tiny computer include an area of audio and video surveillance, oil reservoir monitoring, biochemical process, tiny snail studies, cancer studies and more.
