SAWs can be excited and detected on piezoelectric substrates, crystals with the ability to generate electricity when compressed or vibrated. Electrical components, known as SAW devices, make use of this and provide frequency filtering and sensing in common electronic devices such as mobile phones and touch sensors. But one drawback of SAW devices is that they consume a lot of energy, and thus are a drain on battery life.<\/p>\n<p>The team, which comprised Yoichi Nii and Yoshinori Onose from the Institute for Materials Research at Tohoku University, created a topological waveguide as a solution to this problem.<\/p>\n<p>Waveguides are devices that carry or guide waves in a spatially confined area. Topological waveguides are a recent development that reduce energy loss and allow for manipulating waves in unique ways. The topological nature of the team&#8217;s waveguide minimizes energy consumption and could drastically prolong the battery life of our phones and other electronics.<\/p>\n<p>This waveguide also had the added benefit of being easy to create and compatible with current SAW device <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/technology\/\" data-internallinksmanager029f6b8e52c=\"4\" title=\"Technology\" target=\"_blank\" rel=\"noopener\">technology<\/a>. &#8220;Implementing our waveguide involves simply fabricating nano-sized pillar patterns on the surface of the piezoelectric substrate,&#8221; says Nii.<\/p>\n<p>The waveguide could drive further breakthroughs in quantum technologies. &#8220;SAW based technologies have also attracted the attention of researchers exploring ways to push the boundaries of quantum computing,&#8221; adds Nii.<\/p>\n<div class=\"article-main__more p-4\">\n                                                                                        <strong>More information:<\/strong><br \/>\n                                                Y.
