The energy consumption technologies are running at full speed
The world becomes more and more digital over the years and if we’re not careful we will end up depleting much of our planet’s energy reserves. To this end, scientists are inventing new devices that can work for a long time by using less energy.
The latest electronic device they have developed can function for a full year on a single burst of energy, and this is where a phenomenon known as quantum tunneling comes into play.
The quantum rules of physics apply to the smallest atomic scales, and electrons behave as both waves and particles. The scientists were able to take full advantage of this precise control of the flow of electrons from one side of one circuit to the next. With the help of a 50 million electron jump start, they were able to manufacture this simple and inexpensive device (which consists of only four capacitors and two transistors) for long periods of time.
In order to generate electricity, a device needs to give the electrons inside them a hard pressure known as threshold energy, since the pressure needs to be above a certain threshold. Reaching this threshold can be difficult when you’re designing a device that uses very little power.
Enter quantum mechanics. To overcome this barrier, the electron flow can be controlled in various ways. They could produce the minimal amount of energy needed to move an electron. The end product was a device that leveraged the interplay between internal systems of the toes to identify and collect data without consuming additional power. Such a device can be used to monitor glucose in the blood or to measure the temperature of vaccines during transport. The use of batteries is not required.
