“A Handheld Printer for Physical Sketching of Circuits and Sensors on Everyday Surfaces We present Print-A-Sketch, an open-source handheld printer prototype for sketching circuits and sensors. Print-A-Sketch combines desirable properties from free-hand sketching and functional electronic printing. Manual human control …
“A Do-It-Yourself Technique for Capacitive Multi-Touch Sensing Using a Commodity Microcontroller Mutual capacitance-based multi-touch sensing is now a ubiquitous and high-fidelity input technology. However, due to the complexity of electrical and signal processing requirements, it remains very challenging to create …
“Researchers at Saarland University have created an ultrathin flexible film that can act as a sensor for innovative technologies. Integrated within a glove, the new sensory film can communicate the current position of the wearer’s hand and fingers. By …
“Using machine learning techniques, computer scientists and materials scientists in Saarbrücken have now developed a method that is much more accurate and objective than conventional quality control procedures. Their results have just been published in Scientific Reports, the open-access mega-journal …
“While 3D printing offers great design flexibility before the object is printed, it is very hard for end-users to customize a 3D-printed object to their specific needs after it is printed. We propose HotFlex: a new approach allowing precisely located …
