Indian Insititute of Technology and DRDO (Defence Research and Development Organisation) has developed an underwater Sensor Technology for underwater communications for the Indian Navy. This will enable the communication of various devices at a very low cost.
IIT Madras Researchers Develop Sensor Technology for Underwater Communications
- Researchers at the IIT Madras and scientists of the DRDO have developed cutting-edge sensor technology for underwater communications that the Navy can apply.
- The indigenous technology will enable the fabrication of devices at a relatively lower cost as compared to international foundries, where not only is the cost of fabrication high but also the number of foundries is limited.
- The country celebrates National Technology Day on May 11 and acknowledges the achievements of scientists, engineers, and researchers.
- Known as the piezoelectric MEMS technology it is needed to develop high-performance thin films and convert ‘piezo thin film’, which are a vital component of piezo MEMS devices and are considered for acoustics and vibration-sensing applications.
- The piezo MEMS process recipe has been successfully developed jointly with DRDO team for the complete fabrication of an acoustic sensor, without degrading the functionality of the piezo thin film.
- The fabricated PZT thin film-based acoustic sensor exhibits higher performance than the conventional PVDF-based acoustic sensor. This cutting-edge sensor technology allows the researchers to fabricate high-performance piezo MEMS acoustic devices, which will be advantageous to defence applications.
Main Challenges
- Mr. Varadarajan DRDO Scientist said the main challenge in the piezo MEMS process technology is the need for high reliability and durability in harsh underwater environments, high pressure, and the corrosive nature of seawater.
DRDO
- DRDO works under the administrative control of the Ministry of Defence, Government of India.
- Dr. Samir V Kamat is the incumbent Chairman of DRDO.
- Starting with 10 laboratories, DRDO has now grown to a network of 52 laboratories that are deeply engaged in developing defense technologies covering various disciplines.
Recent Developments by DRDO
- Extreme Cold Weather Clothing System (ECWCS)
- ‘Pralay’.
- Controlled Aerial Delivery System.
- Pinaka Extended Range (Pinaka-ER) Multiple Launch Rocket System (MLRS).
- Supersonic Missile Assisted Torpedo System (SMART).
- Advanced Chaff Technology.
- Akash-NG & MPATGM.
