This wearable device can detect dangerous waves and save lives. Every year hundreds of barnacles risk their lives raffling waves along the coast of Galicia to catch one of the most difficult shellfish to get, the barnacle. The percebeiro shield project for Nissan is a prototype capable of predicting dangerous waves and warning the perished so they can get out in time. The device is incorporated into the neoprene, which integrates perfectly with the work of the percebeiros and alerts them in real time to the behaviour of the sea through different modules.

After a year of research and intensive first-hand collaboration with R & D professionals, oceanographic scientists and authentic percebeiros of the Cofradía de Cangas, we managed to develop a prototype capable of solving the main problems encountered throughout the extraction process of the barnacle. During its development, the Percebeiro Shield technology was tested in different environments besides the Coasts of Galicia, such as the CSIC wave pool.

This technology, which combines visual, sound and physical alerts, manages to give the barnacles a kind of sixth sense to anticipate danger. Using an infrared LIDAR system, the foam produced by the waves is analyzed and used to calculate by algorithm when the dangerous waves come. The system generates alerts, from a dynamic threshold that marks the algorithm itself, which are sent in real time to the wearable device. Once a dangerous wave is detected, the system sends by radiofrequency a signal to the suit. Once received the suit responds with varying degrees of warning to the fisherman.
