A new species of gold frog has been found in an unexplored mountain in southwestern Ethiopia. The species were discovered in just two days after…
IBM company has created world’s smallest computer which is just 0.3mm long and is dwarfed by a grain of rice. It was developed by the University of Michigan.
The name of this microchip is “microdevice”, it is a tenth of the size of IBM’s 1mm x 1mm computer which was launched just a few months ago at their conference “Think 2018”.
Before “microdevice” the smallest computer of the world has been 2x2x4mm Michigan Micro Mote, which could retain its programming and data even when the power is cut off.
Since the unit is so minuscule it cannot have conventional antennas so that receives and transmits data with visible light. A professor of electrical and computer engineering said; David Blaauw is led the development of the new system;
“We basically had to invent new ways of approaching circuit design that would be equally low power but could also tolerate light”.
According to him the device has one slight flaw. It loses all programming capacity and ability to store data when the power is switched off. Blaauw said:
“We are not sure if they should be called computers or not. It’s more of a matter of opinion whether they have the minimum functionality required”.
What usage could such a small device provide?
The developers consider the device can be used in the treatment of certain types of cancer. The microcomputer has the ability to record temperatures in the smallest of areas, such as a cluster of cells, and report it within 0.1 degrees’ Celsius accuracy. Gary Luker, a professor of radiology and biomedical engineering said:
“We are using this temperature sensor to investigate variations in temperature within a tumour versus normal tissue and we can use changes in temperature to determine success or failure of therapy”.
