Worlds Smallest Computer

Have you ever wondered what the worlds smallest computer looks like and if it is really a computer? You know how important the computer is to the advancement of the human race on this planet. That is what this post is about. In this post, we will learn about the world’s smallest computer. You will also know who made it and how it works. worlds smallest computer

Although this computer is tiny, it is useful for health research, oil monitoring, temperature and more. Also, we hope that by the end of this article, you will have all the information you need about the worlds smallest computer. Let us begin.

Worlds Smallest Computer

How did the world’s smallest computer come about?

Let’s take you back memory lane. You will agree with me that if you have the world’s smallest computer, you will also have a big one.

You can define a computer as hardware that carries out computing operations such as calculating, processing data, and storing and receiving of data, etc. The first computer ever created was an electronic digital computer. It can also be called the Atanasoff-Berry Computer (ABC). It was designed by Dr. John V. Atanasoff and Clifford.

In addition, you should note that we had other computers before the creation of the smallest computer. The fact is that it was through the knowledge the engineers got from the existing computer that they used to make the smallest computer. Now that we have this information, let us see some details of the smallest computer.

The worlds smallest computer

IBM’s team of engineers at the University of Michigan designed this computer. You can use this small computer as a cryptographic anchor. IBM created it in March 2018. If you measure the size by a grain of rice, it is 0.33 mm. Also, if you judge the world’s smallest computer by its size, you will think it’s absolutely useless.

However, the device can receive and transmit data with visible light. Its small size makes it impossible for you to use a conventional antenna with it. It also has multiple uses, and we will list some of them now.

The function of the world’s smallest computer

  • Precision temperature sensor:- It is designed to monitor temperatures. It also charges in the region as small as a few cells. This is achieved by converting temperatures into time intervals. It is defined with electronic pulses. It possesses about several hundred thousand transistors.
  • Cancer research:- You can also use the world’s smallest computer to detect and treat cancer. Using the temperature sensor, they are able to test if cancer cells are generally hotter than healthy tissue. With the help of the research, it can help reduce the risk of cancer.
  • To know the causes of tumor
  • Diagnosing glaucoma from inside the eye
  • In addition, you can use the worlds smallest computer to monitor Oil reservoir
  • Biochemical process monitoring
  • Audio and visual surveillance
  • Cuter purpose:- You can use it to study animals, like studying tiny snails.

What are its components?

This also means the general make up of the computer.

  • The Processor:- The problem with this device is that, when it loses power, it also loses all its power. This means you can lose all your data.
  • Memory:- It has static random-access memory (SRAM)
  • A photovoltaic power system (PPS):- The worlds smallest computer contains a Photo-voltaic cell
  • Wireless transmitter and receiver:- You can use this transmitter to transmit and receive information. This you can do by using a light pulse. Also, its transmitter replaces conventional radio antennae.
  • A base station:- The function of a base station is to provide light. The light is for power and programming and also to receives the data.
  • Communications:- It has a LED communications unit and photo-detector.


The computer is a very useful tool for advancing the development of the human race. So, as technology advances the need to make another small computer will increase. Furthermore, you can see from our analysis of the world’s smallest computer how useful it is for health research, oil monitoring, temperature, and more. Also, we advise you to read wide to learn more about new developments in all aspects of life for you to keep developing yourself.
