Coin-sized sensors monitor machine health

Can you imagine coin-sized sensor that can remotely monitor and diagnose the 'health' of a machine without anyone physically inspecting the machine? A*STAR's Institute of Materials Research and Engineering (IMRE) and Singapore's Hoestar PD Technology Pte Ltd are making this concept a reality.

Hoestar has licensed IMRE's piezoelectric sensor technology to automate the monitoring of vibration and physical stresses that impact the efficiency and lifetime of machinery. The technology gives users real-time updates on the physical integrity of the machine and acts as an early warning system to alert users about impending machine failures. Data on deteriorating equipment 'health' allow factories and businesses to plan for a timely replacement of crucial components before they fail completely, thereby minimising costly delays in production. The system also raises productivity by removing the laborious task of manually checking the equipment and reducing the chances of undetected defects due to human error.

The technology uses Hoestar's expertise in diagnosing machine health with IMRE's know-how in piezoelectric and sensor research. IMRE customised its piezoelectric technology so that the extremely miniature millimeter-sized sensing element could be integrated with wireless technology to enable remote monitoring.

"Our piezoelectric sensors are highly miniaturised or can be formed into coating layer which makes installation easy and allows them to be built into machines to give users a more accurate reading of how the machines are doing," said Yao Kui, the scientist who heads IMRE's piezoelectric sensors research. The team from IMRE's Sensor & Transducer Programme was able to develop a sensor prototype with Hoestar in just over a year. "We are also able to integrate wireless technology on the same device to do away with wire connections so that the sensors remain inconspicuous and can be conveniently applied to the moving parts of a machine," Kui added.

"This new system will save companies time, money and labour as the innovative sensor is safer, more accurate and quicker at data collection," said Leong Weng Hoe, managing director for Hoestar, adding that homegrown wireless piezoelectric sensor technology with remote monitoring functions is new to Singapore.

"IMRE's partnership with Hoestar is a clear example of how a local company can work with an A*STAR research institute to employ technology to increase productivity," said Andy Hor, IMRE's executive director. "The capabilities we have built in science and engineering research can help Singapore companies compete better globally."
