Smart vest turns fish into underwater spies, providing a glimpse into aquatic life like never before

Traditional techniques for observing fish behavior, largely dependent on vision-based systems, face substantial limitations, such as a confined range of observation and a limited duration of operation underwater. In response to these challenges, a research team from the National University of Defense Technology has pioneered a wearable electronic device that adeptly captures disturbances in the water flow caused by the movements of fish.
