“…Kim et.al. (2010) designed a piezoelectric energy harvester aiming at increasing the output electric power efficiency by analyzing a finite element method for the structure of the energy harvester [11]. Li, Yuan and Lipson (2011) studied experimentally a piezo-leaf architecture converting wind energy into electrical energy through a wind-induced fluttering motion [12].…”

Vibration dynamic absorber is in use to reduce machinery vibrations. This paper presents a novel idea for using the mass-spring absorber as an energy harvester. The aim is to tune the absorber to cancel the machine vibration and produce maximum vibration of the absorber mass to act as an energy harvester. The main vibrating system is damped and assumed as a SDOF. A new frequency is defined called harvesting frequency at which the amplitude of the absorber mass vibration is maximum. It is shown that his frequency is dependent only on the mass ratio of the absorber and independent of the main system damping ratio. The optimal operation of the proposed system is investigated for damping ratio between 0.1 and 0.4 and mass ratio between 0.05 and 4.5. The absorber succeeds to eliminate completely the main system vibrations at a tuning condition and provides high vibration amplitude at the absorber mass at the new defined harvesting frequency..

/e o value upon heating the specimen at 150°C for 4 h. In an effort to reduce the sintering temperature, CuO was used as an additive for the ceramic. As a result, the CuO-added PZ 0.48 T 0.52 -PZNN ceramic was well sintered at 900°C. In particular, the 1.0 mol% CuO-added PZ 0.48 T 0.52 -PZNN ceramic exhibited a large d 33 value of 554 pC/N and a small e T 33 /e o value of 1620, making it highly suitable for use in multilayer actuators and energy harvesters.
