IIT-Hyderabad researchers use ceramics for knee implants

Posted on Monday, July 8, 2019

The material will help in early detection of implant failures, which will help patients avoid reverse surgery,reports Aparna Sharma

Researchers at Indian Institute of Technology, Hyderabad (IIT-H), are working on a new technology called ‘perovskite-based ferroelectric system’ for the biocompatible implant.
 
This technology will enable the doctors to detect premature failures after performing implant surgery, through non-invasive monitoring and diagnosis, without even performing a reverse surgery. 

“The new technology makes use of piezoelectric and ferroelectric ceramic materials in the implant. During movement, the implant sends electric signals that can be monitored during stress. This helps in detecting the anomalies beforehand and preventing the reverse surgery,” said Saket Asthana, head professor, advanced functional materials laboratory, department of physics, IIT-H.
 
Asthana is working on this project along with his four PhD students since 2016. Since this is a bio-compatible implant, it costs relatively less. The researchers hope to see its use in hospitals soon.
