A new diagnostic tool for machinery can save industries time and money.

Researchers at the Singapore Agency for Science, Technology and Research (A*STAR) have developed and demonstrated a miniature

wireless sensor to remotely diagnose the health of machinery, such as motors, pumps and generators.

The technology works by monitoring the vibrations and physical stresses that impact the efficiency of equipment.

Licensed to Hoestar PD Technology Pte Ltd of Singapore, A*STAR’s piezoelectric sensor technology is designed to provide real-time updates on the physical integrity of a machine and act as an early warning system to alert users about impending failures.

By diagnosing the health of deteriorating equipment, the technology will allow businesses to plan for the replacement of crucial components before they fail, thereby minimising costly production delays. It will also raise productivity by removing the need to manually check equipment and by reducing the chances of undetected defects due to human error.

The prototype technology couples Hoestar’s expertise in diagnosing machine health with A*STAR’s know-how in piezoelectric and sensor research. A*STAR’s Institute of Materials Research and Engineering (IMRE) customised its piezoelectric technology so a millimetre-sized sensing element could be integrated with wireless technology to enable remote monitoring.

Dr Yao Kui, who leads the IMRE team, says their goal for 2014 is to demonstrate the improved performance and operation of a second-generation prototype wireless sensor.

“This new system will save companies time, money and labour as the innovative sensor is safer, more accurate and quicker at data collection,” says Leong Weng Hoe, managing director for Hoestar.
