Material researchers at the INM Leibniz Institute for New Materials will be presenting a composite material which prevents metal corrosion in an environmentally friendly way, even under extreme conditions. It can be used wherever metals are exposed to severe weather conditions, aggressive gases, media containing salt, heavy wear or high pressures.The INM from Saarbruecken will be one of the few German research institutions at the TechConnect World trade fair on 16 and 17 June in Washington DC, USA, where it will be presenting this and other results. Working in cooperation with the VDI Association of German Engineers it will be showcasing its latest developments at Stand 301 in the German Area.This patented composite exhibits its action by spray application, explains Carsten Becker-Willinger, Head of the Nanomers Program Division. The key is the structuring of this layer - the protective particles arrange themselves like roof tiles. As in a wall, several layers of particles are placed on top of each other in an offset arrangement; the result is a self-organized, highly structured barrier, says the chemical nanotechnology expert. The protective layer is just a few micrometers thick and prevents penetration by gases and electrolytes. It provides protection against corrosion caused by aggressive aqueous solutions, including for example salt solutions such as salt spray on roads and seawater, or aqueous acids such as acid rain. The protective layer is an effective barrier, even against corrosive gases or under pressure. After thermal curing, the composite adheres to the metal substrate, is abrasion-stable and impact-resistant. As a result, it can withstand high mechanical stress. The coating passes the falling ball test with a steel hemispherical ball weighing 1.5 kg from a height of one meter without chipping or breaking and exhibits only slight deformation, which means that the new material can be used even in the presence of sand or mineral dust without wear and tear.The composite can be applied by spraying or other commonly used wet chemistry processes and cures at 150-200°C. It is suitable for steels, metal alloys and metals such as aluminum, magnesium and copper, and can be used to coat any shape of plates, pipes, gear wheels, tools or machine parts. The specially formulated mixture contains a solvent, a binder and nanoscale and platelet-like particles; it does not contain chromium VI or other heavy metals.Source: INM - Leibniz-Institut für Neue Materialien

FlexTech Alliance Workshop: Flexible Hybrid Electronics for Wearable Applications Challenges and Solutions
July 10, 2014 - Flexible hybrid electronics (FHE) draws equipment, materials, design and manufacturing processes from two industries: the semiconductor industry and the traditional printing industry. FlexTech Alliance explores this interesting technology merger in a one-day workshop at SEMICON West 2014. One of the fastest growing applications for Flexible Hybrid Electronics is wearable electronic devices for health and human performance monitoring. This workshop will include a review of some of these applications. The semiconductor industry has evolved not only exponentially in terms of capability, but also in the applications it pursues. A recent direction is referred to as More Than Moore. Activity in this space seeks to address needs for more capability for wearable/flexible/conformal systems (even implantable), large size/distributed systems, and low cost (even disposable) sensor and smart packaging systems. Recently, printed electronics has made great progress in materials and processing technologies for flexible, conformable and robust applications such as wearable biomedical sensors and imagers, displays, consumer packaging, and toxic and structural sensors. Almost simultaneously, various techniques are emerging for creating very thin silicon chips and packages as well as flexible PC boards that can be incorporated in flexible systems. Finding ways to cost effectively and reliably integrate conventional processors, MEMS sensors, and high speed RF communications with printed/flexible electronics systems opens the door to wider applications, including wearables. Where do printed/flexible electronics systems offer the best solutions? Where could integrating traditional silicon into a flexible electronics format make most sense for cost or performance? What are the industry-wide challenges and promising solutions for process integration, handling, packaging, and testing hybrid silicon and flexible approaches? Join with subject matter experts and end users to answer these and other pertinent questions.
