自半个世纪前激光器发明之日起，科学家就设想利用类似的原理创造激声器，用声代替光。过去几十年这一概念进展甚微。直到2009年，加州理工和诺丁汉大学的研究人员利用传统激光器激发出声子束，证明激声器实际可行。现在，日本NTT基础研究实验室研究人员让激声器的研究前进了一大步，不需要借助激光器，他们在芯片上制造出完整的机电谐振器。这一发明使得激声器可以与其它设备更容易的整合在一起，超高清医学成像，紧凑低功耗高频率时钟脉冲发生器等应用将触手可及。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.
