Researchers on the Indian Institute of Technology Madras and scientists of the Defence Research and Development Organisation (DRDO) have developed a cutting-edge sensor technology for underwater communications that the Navy can apply.
The indigenous technology will allow the fabrication of units at a comparatively decrease value as in comparison with worldwide foundries, the place not solely is the price of fabrication excessive but additionally the variety of foundries is restricted.
The nation celebrates National Technology Day on May 11 and acknowledges the achievements of scientists, engineers and researchers.
Known because the piezoelectric MEMS technology it’s wanted to develop high-performance skinny movies and convert ‘piezo thin film’, that are a significant element of piezo MEMS units and are thought-about for acoustics and vibration-sensing purposes.
The piezo MEMS course of recipe has been efficiently developed collectively with DRDO crew for the whole fabrication of an acoustic sensor, with out degrading the performance of the piezo skinny movie.
The fabricated PZT skinny film-based acoustic sensor displays larger efficiency than the traditional PVDF-based acoustic sensor. This cutting-edge sensor technology permits the researchers to manufacture high-performance piezo MEMS acoustic units, which shall be advantageous to defence purposes.
The analysis was led by IIT Madras professors Amitava Das Gupta and Boby George together with E. Varadarajan, scientist and V. Natarajan, senior scientist of DRDO on the DRDO Industry Academia – Ramanujan Centre of Excellence (DIA-CRoE) within the institute.
Mr. Varadarajan mentioned the primary problem within the piezo MEMS course of technology is the necessity for excessive reliability and sturdiness in harsh underwater surroundings, excessive strain and corrosive nature of seawater.
