The Defence Research and Development Organisation’s (DRDO) Young Scientists’ Laboratory for Smart Materials (DYSL-SM) in Hyderabad is spearheading a pioneering project aimed at revolutionizing underwater communication for divers. The initiative focuses on developing a “Full Face Mask with underwater wireless cum wired communication system,” leveraging cutting-edge technology to enhance diver safety and operational efficiency.
The primary aim is to indigenize underwater communication systems, reducing reliance on imported technology and fostering self-reliance in India’s defense capabilities.
The project utilizes piezoelectric transducer technology combined with advanced signal processing to ensure clear communication in the challenging underwater environment. The Full Face Mask (FFM) will feature both wireless and wired communication capabilities, allowing divers to switch modes based on operational needs, thereby offering flexibility in various underwater scenarios.
Each unit will be equipped with inbuilt batteries to power the communication system, making it independent of external power sources. These components will convert electrical signals into sound waves for communication and vice versa, ensuring compatibility with the dense medium of water. Advanced algorithms will be used to filter noise, enhance signal strength, and ensure clear voice communication.
Both the transmitter and receiver units, integrated with transducers, will be fully immersed in water, enabling voice communication. The mask design will ensure that these components are effectively sealed yet functional in an aquatic environment.
