Energy Harvesting methods are the most important area of Research since last decade, to bring forward the alternative methods for conventional power sources and generators at microscale and low powered devices. Most of these techniques use the ambient energy present in the environment ... En savoir plus
Depletion layer MEMS actuators have been demonstrated in the past in p-n junctions as well as Schottky barrier interfaces to be effective transducers for internal transduction of high Q MEMS resonators without the need for piezoelectric materials or small resonator-electrode gaps. ...

Ultrasound transducers are regularly used in medical clinics but their performance is known to deteriorate over time. Causes of this image quality degradation can include delamination between layers, physical breakage of components, short circuits and weakening crystals. Regular ... En savoir plus
In order to exploit the piezotronic effect of Zinc Oxide (ZnO) crystal and to design an optimal high gauge strain sensors. One would require a deep understanding of the dynamics of charge carrier transport and accurately predict the levels of mechanical stress field and electrical charge ... En savoir plus
Scanning field emission microscopy (SFEM) is a technique based on Topografiner [1] and Scanning Tunneling Microscopy (STM) [2] technologies. In this work, we do SFEM experiments to measure the electrons emitted by a sharp tungsten tip once they are back-scattered by a W(110) surface with ... En savoir plus
The focus of this work is to determine the potential for arrays of nanoscale bowtie antennas for light enhancement and direction control in nano-optics devices. This is achieved by studying the effects of illumination on the backscattered and total fields, along with the intensity of the ... En savoir plus
Interacting with digital devices has become part of daily life, whether in consumer products, services, or industrial applications. Most display-based devices provide user interactivity through touch sensing via a touch panel. As the number of device features increases, it demands an ... En savoir plus
The development of new experimental techniques designed to measure the thermal response of semiconductors at reduced length and time scales is revealing the requirement of generalized heat transport models beyond the classical Fourier law [1,2]. We present the Kinetic Collective ... En savoir plus
Evonetix is a Cambridge-based start-up company working on a revolutionary new technology to synthesize high-fidelity DNA at scale. Our technology is based on a silicon MEMS chip with a large number of reaction sites that facilitate multiple parallel synthesis channels. We operate a ... En savoir plus
In our work, simulations of a piezoelectrical micromachined ultrasonic transducer compatible with CMOS-MEMS process are presented. The piezoelectric material of the PMUT is AlN sandwiched between two Al layers and a top Si3N4 passive layer. The piezoelectric and the metal materials have ... En savoir plus
