Years go by and technological devices are increasingly created smaller. We ask ourselves: with what intention? , some experts will say for convenience others for competition with state-of-the-art equipment. As far as the smallest computer in the world is concerned, it is for use in medicine.
The image of Banner shows a very small square compared to a grain of rice. They make us understand how tiny the object is much more than what IMB announced, which used a grain of salt as a reference. It is said that this mini computer is ten times smaller.
This sensor is designed primarily to analyze the temperature of a group of cancer cells.
This invention can not have a radio antenna, to send and receive information, so it uses a special LED, changing the diodes by switched capacitors. The light sent by a base station transmits the data, and also energy; and read the pulses of light with which this tiny computer communicates with it. Like IBM's, it has no permanent memory: if it goes out, it loses all the data collected.
