Michigan Micro Mote – The World’s Smallest Computer




The battle of the world smallest computer is something the researchers at the University of Michigan don’t attempt to give up anytime soon with the introduction of the Michigan Micro Mote, a computer smaller than a grain of rice.

Michigan Micro Mote – The World’s Smallest Computer

The Michigan Micro Mote has helped researchers at the University of Michigan remain top in the competition of the creation of the world’s smallest computer. IBM took the title in March 2018 with the release of their 1mm x 1mm computer that measured smaller than a grain of fancy salt at its Think 2018 conference; however, the Michigan Micro Mote has put the University of Michigan back at the top.

One major talk about the new computer built and even the previous one by IBM is if the so-called computer can be called a Computer. Reason being, it is hard to decide if the micro mote is a computer or not since they don’t satisfy some computer requirements like the ability to keep data when power runs out.

According to David Blaauw, a professor of Electrical and Computer Engineering at the University of Michigan,

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.

Be low are the features and capabilities of the Micro Mote:

  • It cannot retain programming and data once there is a power loss
  • This super tiny computer uses photovoltaics: a way of converting light to electricity to enable an exchange of data.
  • It has a base station which provides light for power and programming. It also receives data. Light from the base station and the transmission LED (Light Emitting Diode) creates currents in the tiny circuits.
  • There are wireless transmitters for transmitting data with visible light.
  • Presence of precision sensor to convert temperature into time intervals that come with electronic pulses.
  • The Michigan Micro Mote has a LED, system memory and a processor.
  • Dimensions of the computer are 0.3 by 0.3 by 0.3mm. It is shorter than a grain of rice.
  • Can measure temperature in super tiny regions such as a cluster of cells, with an accuracy of 0.1 degree Celsius.
