The World’s Smallest Computer is Tinier Than a Grain of Rice

Just months after IBM wowed us with the world’s smallest computer, we have a new entrant that has stolen the crown which IBM had only earned this March.

Developed by researchers at the University of Michigan, the new ‘computer’ is ten times smaller than the one produced by IBM, measuring only 0.3 millimeters.

Due to its incredible size, some major changes had to be made that may require rethinking what it takes to build a computer.

How it Works

It comes with light-sensitive diodes instead of capacitors for power since it uses a photovoltaic power system for both data transmission and for power. It still comes with an ARM Cortex-M0+ processor, RAM and a wireless transmitter and receiver. It doesn’t hold any data once it loses its power, however, which should hinder its claims as the world’s smallest computer.

As you’d expect, the computer doesn’t do a whole lot of stuff, though, its applications are expected to be present in the health sector, which shouldn’t be an issue as the little computer is biocompatible.

Possible Uses

It’s expected to aid cancer research by measuring the temperature of cancerous tumors which have for long been expected to be hotter than normal cells, though, we didn’t have a means of verifying this.

Further, it could sit inside the eye and look out for possible signs of glaucoma, study tiny organisms or make sure when treatment is working or not. Uses outside of health monitoring lie in the fields of surveillance and oil drilling.

So, no matter whether one thinks whether it is an actual computer or not, the tiny device will find ways to be helpful.
