The goal of this partnership is to develop cheap, portable, infrasonic sensors than can be deployed across existing infrastructure (i.e. smart cities, weather stations, lightning networks, etc.) for the early warning of extreme atmospheric, geologic and climatic events. Acoustic waves at frequencies lower than the human hearing range (i.e., f < 20 Hz), known as infrasound, are emitted by an impressive set of physical phenomena such as tornados, hurricanes, volcanic eruptions, earthquakes, tsunamis, nuclear explosions, and heavy machinery operation. Tornados and volcanos are notably known to produce infrasound that can be detected remotely, 15 - 45 minutes before destruction occurs. Better detection of infrasound can therefore provide early warning on the occurrence of such extreme events, with the potential to save lives and reduce related economic losses.Working with our industrial partner Soundskrit, our goal is to research, extend, and develop emerging microphone technologies, originally intended for consumer electronics, to infrasound sensing. By leveraging the economies of scale achievable through MEMS manufacturing, we aim to offer better performance at a significantly lower cost than existing infrasound microphones. This could enable the cost-effective deployment of this novel infrasound sensor technology into a variety of existing infrastructure such as weather towers and into millions of personal electronic devices (e.g., cellphones, smart homes). Integrating these devices with the ever-increasing web of the Internet of Things could, in turn, ultimately enhance our early warning systems for a range of potentially disastrous events..

该合作伙伴关系的目的是开发便宜，便携式，室内传感器，而不是在现有基础设施（即智能城市，气象站，闪电网络等）中部署的早期警告。低于人类听力范围（即f <20 Hz）的声波，称为Infrasound，是由令人印象深刻的一系列物理现象（例如龙卷风，飓风，火山喷发，地震，海啸，海啸，核爆炸和重型机械机器操作）散发出来的。众所周知，龙卷风和火山会产生可能在破坏发生前15-45分钟远程检测到的侵蚀。因此，更好地检测出侵蚀的可能会为发生这种极端事件的发生提供预警，并有可能挽救生命并减少相关的经济损失。与我们的工业合作伙伴Soundskrit一起工作，我们的目标是研究，扩展和开发最初用于消费者电子产品的麦克风技术，以降低感应。 通过利用可通过MEMS制造实现的规模经济经济，我们的目标是以比现有的Infrasound Mactophone的成本低得多的成本提供更好的性能。 这可以使这种新型的Infasound传感器技术的成本效益部署到各种现有的基础设施中，例如气象塔和数百万个个人电子设备（例如，手机，智能房屋）。 将这些设备与不断增加的物联网网络集成在一起，反过来最终可以增强我们的预警系统，以实现一系列潜在的灾难性事件。
