The noncentrosymmetric nature of single-layer (SL) transition-metal dichalcogenides (TMD) manifests itself in the finite piezoelectricity and valley-Zeeman coupling. We microscopically model nonlinear exciton transport nanobubbles SL TMDs. Thanks to giant piezoelectric effect, we obtain an enormous internal electric field, ${E}_{\mathrm{piezo}}\ensuremath{\sim}{10}^{7}\phantom{\rule{0.16em}{0ex...

This project was developed to need for a system that generates non conventional energy. Energy crisis is one of the major issues worldwide. paper proposes maximum utilization human locomotion energy power generation using Piezo electric sensors. The basic principle was, any vibration or pressure generate between surface and footsteps while walking, converted into transducers. A series connectio...

Phase modulators are one of the key components of many applications in electromagnetic and opto-electric wave propagations. Phase-shifters play an integral role in communications, imaging and in coherent material excitations. In order to realize the terahertz (THz) electromagnetic spectrum as a fully-functional bandwidth, the development of a family of efficient THz phase modulators is needed. ...

The major requirement of implantable biomedical equipment like pacemaker, hearing aid device must have low power consumption and reliability. In order to provide a power to this biomedical equipment’s a new approach is presented in this paper, to extract electric power from heat of the subject or human body. Hereby the surgeries for battery implantation in the subject or human body can be avoid...

In this paper, a new non-contact ultrasonic abrasive finishing mechanism is designed and fabricated. This mechanism combines the function of ultrasonic vibrations and the magnetic abrasive finishing (MAF) process. A permanent magnet which is mounted on a horn has been used as the processing tool. This polishing tool is vibrated at an ultrasonic frequency with piezo-electric actuators. Ultrasoni...

Significant economic and technical benefits accrue from the use of pre-existing and commercially available software components to develop new systems. However, challenges remain that, if not adequately addressed, will slow the adoption of software component technology. Chief among these are a lack of consumer trust in the quality of components, and a lack of trust in the quality of assemblies o...
