NTU's 'sense-ational' invention helps underwater vessels navigate with ease
Date:12/12/2012

on of these MEMS sensors, which specialises in near-field detection include defence applications. These can detect nearby submarines without the use of sonar thatgives away one's location.

This collaborative research resulted in two breakthrough papers being accepted for presentation at a prestigious MEMS conference next January in Taiwan, organised by the Institute of Electrical and Electronics Engineers (IEEE).

One paper is for the development of the piezoelectric sensor which does not require any energy as it generates an electric voltage when water flows past the 'feelers'. The second paper focuses on a low-powered biomimetic sensor which can detect underwater objects even when there is little water flowing past it.

To further improve the sensor, Prof Miao's team is now looking to develop a hybrid sensor which will combine both the zero-energy piezoelectric sensor's high accuracy with the low-powered static sensor's ability to detect objects in still water.
