• A team led by an Indian-origin scientist has developed a novel device that could increase the battery life of electronic devices, such as smartphones and laptops, by more than a hundred-fold.
  • Researchers from the University of Missouri in the US developed a magnetic material that employs a unique structure — a “Honeycomb” lattice that exhibits distinctive electronic properties.
  • Semiconductor diodes and amplifiers, which often are made of silicon or germanium, are key elements in modern electronic devices
  • The new material conducts unidirectional current, or currents that only flow one way.
  • The material also has significantly less dissipative power compared to a semiconducting diode, which is normally included in electronic devices.
  • The magnetic diode paves the way for new magnetic transistors and amplifiers that dissipate very little power, thus increasing the efficiency of the power source.
  • This could mean that designers could increase the life of batteries by more than a hundred-fold. Less dissipative power in computer processors could also reduce the heat generated in laptop or desktop CPUs.
  • Although more works need to be done to develop the end product, the device could mean that a normal 5-hour charge could increase to more than a 500-hour charge
  • The device could also act as an ‘on/off switch’ for other periphery components such as closed-circuit cameras or radio frequency attenuators, which reduces power flowing through a device.
