Energy Harvesting is Not Fiction Anymore
“About what we did dream today, are the ideas from tomorrow. The tomorrow ideas are the products from the days after tomorrow.” Our environment is changing and everything is becoming “electronified”. Our glasses, our hand gloves, shirts, shoes etc., can be connected already today with our smartphones and can send commands to the machinery surrounding us. We want this comfort, … [Read more...]
Photo Etching Thin Titanium Components
Tech-Etch specializes in the photo chemical etching of titanium. Because of its low weight, strength and corrosion resistance, titanium is used in everything from jet engines to eyeglass frames. Because titanium is inert and completely biocompatible, it is also used in many medical implantation applications such as maxillofacial and craniofacial reconstruction plates, as well … [Read more...]
