This paper presents an experimental study to support the concept of generating energy by a continuous flow of water using piezoelectric sensors. This study is aimed to determine the effect of external force direction of continuous water flow, i.e., vertic... see more

Samples of 0.96(K0.48Na0.48Li0.04)(Nb0.95Sb0.05)O3-0.04Bi0.5(Na0.82K0.18)0.5ZrO3 piezoelectric ceramic were fabricated with conventional ceramic techniques and sintered at different temperatures. The effect of sintering temperature (TS) on the struct... see more

The concept of harvesting energy in the ambient environment arouses great interest because of the demand for wireless sensing devices and low-power electronics without external power supply. Harvesting energy by vibration with piezoelectric materials can ... see more

Different compositions of (Pb1-xLax) (Zr0.60Ti0.40)O3 (abbreviated as PLZT x/60/40; x=0, 0.07, 0.08 and 0.10) ceramics were prepared by a combinatorial approach by high energy mechano-chemical ball milling and cold isostatic pressing (CIP). X-ray diffract... see more

Diagnosis according to Ayurveda is to find the root cause of a disease. Out of eight differentkinds of examinations, nadi-pariksha is very important. By checking the pulse, the Ayurvedicphysician finds the predominant dosha out of the three - vata, pitta ... see more

This paper gives an insight into the piezoelectric gyro sensor technology including theprinciple of operation, performance-limiting phenomenon, etc. With a brief account ofconventional gyro sensor technologies, a detailed discussion on piezoelectric vibra... see more

The IEEE standard on piezoelectricity recommends methods to determine the coefficientsof piezoelectric ceramics and the sizes of the samples to be used. A method to determine thedifference between the actual coefficients and the coefficients determined us... see more

Conventional ceramic piezoelectric materials have been used in hydrophones for sonarapplications since 1940's. In the last few years since the discovery of polymeric piezoelectrichydrophones, the technology has matured, applications have emerged in extrao... see more

Piezoelectric actuators are the potential actuators having a wide range of applications insmart structures and systems. However, the presence of hysteresis nonlinearity leads todegradation in their performance. This paper discusses a mathematical model fo... see more
