University of Michigan Research Team Develops a Computer Smaller Than Rice Grains

The IBM Corp. launched the world’s smallest computer at the beginning of the year. The computer is 1mm x 1mm. However, the research team at the University of Michigan has continued to push its limits. The U.S. researchers at the University of Michigan have only 0.04 cubic millimeters of this computer. Even our common rice grains are many times larger.
Of course, both IBM and the University of Michigan have determined whether these devices are computers because data such as dates will be lost after a power outage. This AMD computer mainly relies on light to excite current-driven circuits and sensors. Due to size restrictions, the device cannot even install conventional radio antennas.
The sensor it carries is mainly a temperature sensor that is extremely sensitive to temperature. The researchers hope that the computer can lurk around the cells to monitor the temperature.
A medical research team believes that the cancer tumor area temperature will be slightly higher than other tissues, so monitoring with a temperature sensor can determine whether cancer has occurred.
However, this conclusion has not yet been confirmed by more researchers, but this does not prevent other research teams from developing cutting-edge medical equipment for this conclusion.
As far as data transmission is concerned, because conventional transmission methods cannot be used, the researchers turned the temperature into time intervals and transmitted data through electrical pulses. Of course, don’t look at the ultra-computing machine’s body, but actually, it is also equipped with researchers based on ARM Cortex-M0+.
According to the ARM official introduction of such embedded technology, the processor clocked at only 2.46MHz, but the advantage is that the body is small and the power consumption is very low.
