Researchers at the Indian Institute of Technology Madras (IITM) and the Defence Research and Development Organisation (DRDO) have developed a new sensor for underwater communications. This technology is expected to facilitate communication between divers and underwater vehicles or submarines.
The underwater communication system is a vital component in defence and civilian operations such as oil exploration and environmental monitoring. However, conventional radio frequencies cannot transmit signals underwater due to the high absorption of electromagnetic waves. To overcome this challenge, the team developed a new sensor that can pick up signals from acoustic communication systems.
The sensor uses the piezoelectric effect to convert sound waves into electrical signals. These signals are then amplified and processed by a microprocessor, allowing the system to decode and transmit messages to divers and underwater vehicles. The device can detect acoustic signals up to a range of 100 meters and can operate in a temperature range of 0 to 60 degrees Celsius.
The new technology is expected to make a significant impact in defence operations. For instance, it can enhance the communication between divers and submarines during rescue missions and covert operations. In civilian operations, the sensor can facilitate underwater exploration and monitoring, including oil and gas exploration and oceanic studies.
In conclusion, the collaboration between IIT Madras and DRDO is a significant milestone in the field of underwater communication technology. The new sensor technology can revolutionize underwater communication, improving safety and efficiency in defence and civilian operations.
