Book Description This monograph covers the fundamentals, fabrication, testing, and modeling of ambient energy harvesters based on three main streams of energy-harvesting mechanisms: piezoelectrics, ferroelectrics, and pyroelectrics. It... more
Pulse detonation is a propulsion technology that involves detonation of fuel to produce thrust more efficiently than current engine systems. By literature survey and library research it is shown that Pulse Detonation Engine (PDE)... more
This paper focuses on the primary development of novel numerical and analytical techniques of the modal damped vibration energy harvesters with arbitrary proof mass offset. The key equations of electromechanical finite element... more
The electro-mechanical impedance (EMI) technique has so far been very successful in monitoring structural components made of both metals and nonmetals in the fields of civil, mechanical and aerospace engineering. In the last two decades,... more
Presented here is a patent in the Bulgarian register of inventions (Reg. № 41177/1978), written in Bulgarian. The patent relates to uniform deposition of semiconducting and insulating thin films in cold gas plasma. Various flat substrates... more
After a piezoelectric inkjet printhead jets the first droplet, the actuating membrane still vibrates, creating residual vibrations in the ink channel, which can degrade the inkjet printhead performance. For suppressing these vibrations,... more

We report a multiple resonant mode film bulk acoustic resonator (FBAR) with different AlN film thicknesses of 605 nm, 640 nm and 680 nm. With the tilted c-axis orientation of the AlN piezoelectric film providing polarization vertical to... more
In this article, a piezoelectric energy harvesting has been developed experimentally and theoretically based on Euler-Bernoulli Theory. A PVDF piezoelectric thick film has attached along of clamped-clamped beam under sinusoidal base... more
El medidor de fuerza aquí presentado está constituido básicamente de tres etapas. La primera etapa (etapa sensor) está constituida por el sensor piezoresistivo FlexiForce modelo A201, que fue escogido debido a sus múltiples propiedades... more
The transformation of vibrations into low-power electricity has received growing attention over the past couple of decades. The goal in this research field is to power wireless sensors and other small electronic components by harvesting... more

Based on an anisotropic phase field model, the morphological evolution and migration of inclusions in piezoelectric films under mechanical and electric loads are investigated. An order parameter field is introduced to characterize the... more
We used pulsed laser deposition to grow a series of PbTiO3/PbZr0.2Ti0.8O3 superlattices on SrTiO3 and SrRuO3/SrTiO3 substrates. An a/c polydomain structure was evidenced by reciprocal space mapping and by transmission electron microscopy.... more
