What Are Spintronics? How Do They Work?

Electronic devises and moving mechanics has long been dominated by the charge of electrons, but a revolutionary field known as spintronics is shifting the conversation. So what are Spintronics? Or spin electronics, exploits the spin of electrons, alongside their fundamental electronic charge, to develop new technologies that promise an enhanced performance. But what does this all mean? What exactly are spintronics? How do you build a spintronic device? Read on to learn more about this trending magnetic discovery.

It’s not all science and tech, Spintronic technology can be used for creative purposes too. By manipulating magnetic fields and electric currents to create dynamic visual effects. For example:

By integrating spintronic sensors, sculptures can respond to the presence and movements of viewers. For instance:

  • Spin-Valve Sensors: These can detect changes in magnetic fields and be used to trigger motors or actuators. An interactive sculpture or animatronic could move, change shape, or light up based on the proximity and movement of people around it.

Spintronics-based memory elements, such as MRAM, can be used to create sculptures that “remember” interactions:

  • Stateful Sculptures: These sculptures can change their configuration based on viewer interactions and retain these changes even after being powered off. For instance, a sculpture might alter its form in response to touch or sound and keep this new form until reset.

Using MRAM to record interactions you can build a piece that not only has certain triggers that creates an action but also stores these in. Each touch or motion near the magnet could trigger a range of changes that is stored in memory, allowing the sculpture to evolve over time based on viewer engagement.
