Vibration energy harvesting technology can capture ambient forms. Using an shock absorber (EHSA) is one of the methods to achieve this function. The EHSA with mechanical motion rectifier (MMR) has bifurcation, which improve performance and reduce impact between gears. However, bifurcation makes it difficult quantitatively predict vibrational dissipation MMR−EHSA. Evaluating MMR−EHSA during desi...

This study investigated the impacts of different notification modalities used in low and high ambient sound environments for mobile phone interaction. Three modalities—Shaking Visual, Shaking Visual + Vibration, Vibration—were designed experimentally tested by asking users to conduct a maze task. A total 72 participants were invited take part experiment through convenience sampling method. The ...

The concept of “energy harvesting” is to design smart systems to capture the ambient energy and to convert it to usable electrical power for supplying small electronics devices and sensors. The goal is to develop autonomous and self-powered devices that do not need any replacement of traditional electrochemical batteries. Now piezoelectric cantilever structures are being used to harvest vibrati...

Vibration energy capture devices can convert the mechanical from ambient source into electrical energy. The captured provide for low-power such as microelectromechanical systems(MEMS) a supplement to power system. has been widely concerned by researchers because of characteristics easy access and green. conversion vibration be achieved electromagnetic, electrostatic, piezoelectric, magnetostric...

The importance of bridge health monitoring and management has been recognized by authorities of long-span bridges throughout the world in recent years. The GeoSHM consortium, led by the University of Nottingham, was awarded a Feasibility Study (FS) grant in 2013 by the European Space Agency (ESA) to investigate how to use integrated GNSS and Earth Observation technologies for the structural hea...

Energy harvesting from vibration for low-power electronics has been investigated intensively in recent years, but rotational energy harvesting is less investigated and still has some challenges. In this paper, a methodology for low-speed rotational energy harvesting using piezoelectric transduction and frequency up-conversion is analysed. The system consists of a piezoelectric cantilever beamwi...
