A SMART vibration sensor with wireless communication for recording and analysing train vibration has been developed in the country.

Alka Dubey and Ashish Verma of Sagar University brought this innovation to light, while presenting their paper at the fourth international Wireless Communication Sensor Networks concluded at Indian Institute of Information Technology-Allahabad (IIIT-A) on Monday (Dec 29).

Dubey said that high speed trains are one of the most impressive developments of the recent years having brought a new degree of comfort for travelers. These trains posed serious accidents because of the high level of vibration, which are generated. Therefore to make the train speed smoother, a smart vibration sensor is developed. It is a self sensation device equipped with recording and wireless communication interface.
