无绳灯泡由美国麻省理工学院研究人员研制。科学界期望把这一技术拓展到其他领域,最终实现手机、笔记本电脑等设备的无线自动充电。无线输电去年秋天,麻省理工学院物理学教授马林·索尔贾希克却提出一种可以通过“无线电能传输”技术利用电磁能的新理论。按照索尔贾希克的理论,只要让电磁能发射器同接收设备在相同频率上产生共振;它们之间就可以进 Cordless light bulbs were developed by researchers at the Massachusetts Institute of Technology. The scientific community expects to expand this technology into other areas and eventually realize wireless automatic charging of mobile phones, laptops and other devices. Wireless Transmission Last fall, Marin Soljasik, a professor of physics at the Massachusetts Institute of Technology, proposed a new theory that could use electromagnetic energy through the “radio energy transmission” technology. According to Soljak’s theory, as long as electromagnetic energy transmitters and receivers resonate at the same frequency; they can enter
