Smaller than a Rice, This Computer Can Measure Temperature
Some time ago, the company computers from the US, IBM introduced the computer the smallest in the world that is smaller than a grain of salt. It seems, the mini computer will have a competitor. The University of Michigan has just introduced their 0.03 cubic-meter "computer" measuring artificial temperatures. Compared to IBM's mini-computer, it's about a tenth smaller. Measure is even much smaller than a grain of rice.
So small, the transmission LED is also shrunk, so it can trigger the current on the circuit board. The researchers had to rack my brain to reduce the impact of the lightness of the device. They try to swap the diodes with capacitors and suppress the relative increase in electricity. The increase comes from devices running on very weak power. As a result, the sensor is able to measure changes in temperature in a very small area, such as cell groups in the human body.
This tiny device can be used for medical purposes. For example, researchers who suspect if the tumor has a temperature slightly hotter than healthy tissue. But until now, it is still difficult to be studied more deeply. With these mini-devices, these claims can be reviewed and if proven, then the effectiveness of cancer treatment can also be measured for success. The researchers also hope to help diagnose glaucoma from within the eye, monitor the biochemical process and also study very small snail animals.
Completeness "computer" this small certainly can not be aligned with the concept of computers in general are able to process, retrieve and store data. Even the mention of the term "computer" for this micro-device is still debated. "We're not sure whether they should be called a computer or not, it's more of a question of whether they have the necessary functionality," said David Blaauw, a professor of electrical and computer engineering at the University of Michigan.
Summarized KompasTekno from Engadget , Tuesday (26/06/2018), this computer is equipped processor based on ARM Cortex-M0 Plus design. However, if the device loses power, then all data will disappear, just like IBM's mini-computer.
