I-Corps: Light Modulated Acoustic Devices

该提案建议将光调制声学器件（LMAD）技术商业化，将光子材料的基础研究从实验室转化为市场。利用光主动控制声音具有挑战性，并且由于声波和电磁波的性质的根本差异而被认为是声学技术的圣杯之一。PI和他的团队建议将该技术商业化，以利用嵌入声子晶体中的纳米颗粒的新型介电特性远程光主动控制声子特性。由于声子学处理振动，声学或其他方面，潜在的应用范围从车辆和设备的主动非接触式振动阻尼，到智能高分辨率超声技术，再到主动减少噪音污染的环境技术。LMAD是光子学、声子学技术的子类别的一部分。通过这种技术，将在现有的聚焦声技术中实现更大的动态灵活性。用于振动阻尼的有源选择性过滤元件可以用于过滤掉所选择的不想要的振动模式。典型的客户包括超声波设备的制造商，用于热生物医学，成像或结构表征应用。

This proposal proposes to commercialize the technology, Light Modulated Acoustic Devices (LMAD) to translate basic research on photonic materials from the laboratory to the market place. Controlling sound actively using light is challenging and is considered to be one of the holy grail of acoustics technology due to the fundamental differences in the nature of the acoustic and electromagnetic waves. The PI and his team propose to commercialize the technology to photo-actively control phononic properties remotely using the novel dielectric properties of nanoparticles embedded in phononic crystals. Since phononics deals with vibrations, acoustic or otherwise, potential applications range from active, non-contact vibration dampening for vehicles and devices, to smart, high resolution ultrasound technology, to environmental technologies to actively reduce noise pollution. LMADs are part of the subcategory of technology of photonics, phononics.Greater dynamic flexibility in existing focused-sound technologies will be achieved via this technology. Active selective-filtering element for vibration dampening can be used to filter out selected unwanted vibration modes. Typical customers would consist of manufacturers of ultrasonic equipment for either hyperthermic biomedical, imaging, or structural characterization applications.
