Our Oceans IoT technologies enable new applications in climate and ecological monitoring, aquaculture, energy, and robotic navigation.
Bringing massive connectivity to low-cost, low-power ocean sensors is important for numerous oceanographic applications across climate/weather modeling, marine biology, aquaculture, and defense. However, standard IoT technologies (e.g, Bluetooth, WiFi, GPS) cannot operate underwater, which has left 70% of our planet (the ocean) beyond their reach. Our research is changing this reality by inventing IoT technologies that are inherently designed for the ocean. By rethinking the entire IoT technology stack in the context of oceans, we introduced low-cost (< $100), net-zero-power, scalable connectivity technologies that seamlessly operate underwater and pave the way for massive underwater sensing, networking, localization, imaging, and machine learning.
How can we enable a batteryless ocean IoT?
We developed Piezo-Acoustic Backscatter (PAB), the first technology that enables backscatter networking in underwater environments. PAB relies on the piezoelectric effect to enable underwater communication and sensing at near-zero power. Check out the video below and our paper to see how it works.
