In a recent report, Xiaolei Peng and a team of scientists in materials science and engineering at the University of Texas, U.S., and the Tsinghua University, China, developed opto-thermoelectric microswimmers bioinspired by the motion behaviors of Escherichia coli (E. coli). They engineered the microswimmers using dielectric gold Janus particles driven by a self-sustained electric field arising from the optothermal response of the particles. When they illuminated the constructs with a laser beam, the Janus particles showed an optically generated temperature gradient along the particle surfaces, forming an opto-thermoelectrical field to propel themselves along. /news/2020-09-opto-thermoelectric-microswimmers.html General Â鶹ÒùÔºics Optics & Photonics Fri, 04 Sep 2020 13:10:01 EDT news518442238 Using a combination of theory and experiment, researchers have developed a new approach for understanding and predicting how small legged robots – and potentially also animals – move on and interact with complex granular materials such as sand. /news/2013-03-terradynamics-technique-legged-robots-granular.html Robotics Thu, 21 Mar 2013 14:00:16 EDT news283091775 (Â鶹ÒùÔº)—Researchers at the University of Dundee in Scotland have devised a means of using a Microsoft Kinect sensing system to allow for hand control of holographic optical tweezers. They describe their results in a paper they've uploaded to the preprint server arXiv. /news/2012-11-physicists-kinect-holographic-tweezers-video.html General Â鶹ÒùÔºics Mon, 05 Nov 2012 09:57:28 EST news271331825
