Device Blocks Electromagnetic Waves with the Flip of a Switch MXenes MXene radiation thinfilms DrexelUniv
Jan 17 2023Reviewed by Megan Craig, M.Sc. The innovation, made possible by two-dimensional materials known as MXenes, has the potential to improve the performance of electronic devices, enhance wireless connections, and secure mobile communications from intrusion.
Dynamic control of electromagnetic wave jamming has been a significant technological challenge for protecting electronic devices working at gigahertz frequencies and a variety of other communications technologies. Semiconductors eBook Compilation of the top interviews, articles, and news in the last year.
Without being able to control the ebb and flow of electromagnetic waves within and around a device, it’s a bit like a leaky faucet – you’re not really turning off the water and that constant dripping is no good. Our shielding ensures the plumbing is tight—so-to-speak—no electromagnetic radiation is leaking out or getting in until we want to use the device.
Gogotsi and his Co-Authors note, “These results indicate that the MXene films can convert from electromagnetic interference shielding to quasi-electromagnetic wave transmission by electrochemical oxidation of MXenes. The MXene film can potentially serve as a dynamic EMI shielding switch.”
