NRL Researchers Reinvent the Inductor after 200 Years
Finally, out-evolved Faraday.
A new materials-based approach by Banerjee yields a smaller, higher-performing alternative to the classic design
A basic building block of modern technology, inductors are everywhere: cellphones, laptops, radios, televisions, cars. And surprisingly, they are essentially the same today as in 1831, when they were first created by English scientist Michael Faraday.
The particularly large size of inductors made according to Faraday’s design are a limiting factor in delivering the miniaturized devices that will help realize the potential of the Internet of Things, which promises to connect people to some 50 billion objects by 2020. That lofty goal is expected to have an estimated economic impact between $2.7 and $6.2 trillion annually by 2025.
In 2018 Professor. Banerjee led the demonstration of the first kinetic inductor that exploits a completely new mechanism (kinetic inductance) at room temperature using intercalated graphene and re-invented this fundamental passive device.
