Harvesting Wasted Vibration from Operating Machines

Jointly organised by CAD, EVD, MID and AMC

Programme Highlight

Wireless sensors, which are widely used to capture sensory data from machines for their
health monitoring, are commonly powered by batteries. The need of frequent replacement
of batteries is undesirable as the monitored machine may be located remotely or installed
in a hazardous place. A novel alternative is to recharge the batteries by harvesting wasted
energies, such as vibration and convert it to electricity so as to power the wireless sensor
continuously. Hence, the sensor becomes self-sustainable in power consumption. Since
the destructive vibration has been absorbed, the machine becomes healthier. Moreover,
less deposal of used batteries means less harm to earth.

Ir. Dr. Peter Tse, who is the Director of the Smart Engineering Asset Management Laboratory (SEAM) and the Croucher Optical Nondestructive Testing (CNDT) Laboratory in the Dept. of MEEM of the City University of Hong Kong, was invited and presented a technical seminar with a topic on “A Novel Design of a Energy/Frequency Converter for Harvesting Wasted Vibration from Operating Machines”. The seminar was held in the HKIE Head Quarter on 15 Oct 2010 with over 70 people attended the seminar. The seminar was jointly organized by CAD, EVD, MID and AMC divisions.
