This paper reports a self powered smart sensor node (also called ‘smart tag’) consisting of a piezoelectric vibration energy harvester, a power conditioning circuit, sensors and an RF transmitter. The smart tag has dimensions similar to a credit card and can be easily integrated into various applications such as the ibration energy harvesting iezoelectric generator elf-powered ireless sensor no...

The purpose of this study was to investigate the effect of type of alcohols and humectants in inks formulation, and the papers surface morphology on the ink-jet printing properties. In order to investigate the influence of alcohol and humectant types on printing properties, the optimum ink formulation from previous study, which contained C.I. Reactive Blue 21 Ink2 was formulated with different ...

This study details the use of printing and other additive processes to fabricate a novel amperometric glucose sensor. The sensor was fabricated using a Au coated 12.7 μm thick polyimide substrate as a starting material, where micro-contact printing, electrochemical plating, chloridization, electrohydrodynamic jet (e-jet) printing, and spin coating were used to pattern, deposit, chloridize, prin...

Thin film transistors are at the heart of integrated circuits. Modern computer processor chips can contain more than 2 billion transistors. Such chips are currently fabricated by expensive lithography processes and fabrication facilities can cost more than one billion US dollars. In a future era of cheap, disposable electronics such cost structures will not be practical. Printed electronics how...

Colloidal nanoparticles developed as interesting objects to establish twoor threedimensional super-structures with properties not known from conventional bulk materials. Beyond, the properties can be tuned and quantum effects can be exploited. This allows understanding electronic and optoelectronic transport phenomena and developing corresponding devices. The state-of-the-art in this field will...

the fabrication of complex-shaped parts out of (wt %) co-28cr-6mo alloy by three-dimensional printing (3dp) was studied using two grades of the alloy with average particle sizes of 20 and 75 μm. to produce sound specimens, 3dp processing parameters were tuned. the sintering behavior of the powders was characterized by the dilatometric analysis. batch sintering in argon atmosphere at 1280 °c for...

3D printing has been hailed as a game changer in the manufacturing sector, with major imprints across multiple domains. Players from several industries are investing heavily in 3D printing, with the possibility of extending its applicability to daily use products coming to the fore. With speculation and limited information blurring the line between reality and fiction, it is critical to analyze...

The Electrohydrodynamic-jet (E-jet) printing process combines high resolution printing with a large variety of printing materials, making E-jet suitable for applications ranging from flexible electronics to high resolution biosensors. In this article, we explore a novel E-jet printing application fabricating high-resolution micro-optical devices. Examples given are a microlens array, an optical...

Greater distributed production of energy from renewable resources such as solar radiation has increased fluctuations of power on the electrical grid. Current infrastructure has limited ability to handle continued increases in fluctuations. Predicting weather patterns in areas containing a high penetration of solar photovoltaic installations can allow time to switch to energy storage and inform ...

Nowadays 3D printing allows us to create physical objects on the basis of digital data. Thanks to its rapid development the use enormously increased in medicine too. Its creations facilitate surgical planning processes, education and research in context of organ transplantation, individualization prostheses, breast forms, and others.Our article describes the wide range of applied 3D printing te...
