What they faced was a series of challenges.<\/p>\n<p>The device that OIST researchers aimed for was a \u2018frictionless\u2019 platform. However, the system would lose energy over time without an external power source. This is known as \u2018eddy damping\u2019 since external forces make an oscillating system lose energy.<\/p>\n<p>The other hurdle to overcome would be minimizing the system\u2019s kinetic energy. This is necessary since it can help improve the system\u2019s sensitivity if it were to be used as a sensor. If the kinetic motion can be further cooled to the quantum realm, it could also open up possibilities of more precision measurements.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The technology can also be used to devise a range of advanced sensors for everyday use and to advance science.
