A shape-changing antenna for more versatile sensing and communication
MIT researchers developed a method to design and fabricate reconfigurable antennas with adjustable frequency ranges. Users can adjust the frequency by squeezing, bending, or stretching the material, making the antenna more versatile for sensing and communication than traditional static antennas.
Using the design tool, the researchers incorporated meta-antennas into several smart devices, including a curtain that dynamically adjusts household lighting and headphones that seamlessly transition between noise-cancelling and transparent modes. A user can stretch, bend, or compress the antenna to make reversible changes to its radiation properties, enabling a device to operate in a wider frequency range without the need for complex, moving parts. The result is a simplified design for a reconfigurable antenna that could be used for applications like energy transfer in wearable devices, motion tracking and sensing for augmented reality, or wireless communication across a wide range of network protocols.
