A group of researchers at the Korea Advanced Institute of Science and Technology (KAIST) has synthesized a nanogenerator – a flexible piezoelectric energy harvesting device based on biological templates. The biotemplated nanogenerator is low cost and it can be self-powered by simple finger movements that could be used to power small commercial LCD screens and… »
Scientists at the Korea Institute of Science and Technology (KIST) have succeeded in developing high strength, biodegradable and bioabsorbable Magnesium (Mg), Calcium (Ca) and Zink (Zn) alloys. These alloys have great mechanical properties such as high strength, good tissue compatibility, and medically acceptable corrosion rate. That makes them ideal for next generation of implants used… »
Materials scientists at the Harvard School of Engineering and Applied Sciences (SEAS) have created a new type of transistor that mimics the behavior of a synapse. The synaptic transistor simultaneously modulates the flow of information in a circuit and physically adapts to changing signals. The technology could lead to creation of a new kind of… »
While hydrogen can be found nearly everywhere in the environment and it can be used to produce power, producing and collecting molecular hydrogen with current methods isn’t competitive with other sources of energy. Duke University engineers have developed a novel method for producing clean hydrogen, which could prove essential to weaning society off of fossil… »
Researchers at Georgia Insittute of Technology (Georgia Tech) developed arrays piezotronic transistors capable to convert mechanical motion into electronic signals. Named “taxels”, these touch-sensitive transistors could provide significant improvements in resolution, sensitivity and functionality for tactile sensing. The arrays could aid in robotics as tactile sensors, provide better security in handwritten signatures and offer new… »
Analogous to way old camera films recorded light exposition onto photographic film, image sensors in digital camera convert the light from the lens to our digital photos. Researchers at the Technische Universität München (TUM) have developed image sensors that consist of electrically conductive plastics which are more sensitive to light compared to their conventional silicon… »
Alongside the usual news and articles about breakthroughs in energy storage and generation, there were many breakthroughs in materials science and biomedicine during the last year. Development of 3D chips is gaining its momentum, and there are many attempts to utilize low-value materials that were usually discarded after some other production process, as well as… »
A group of researchers from the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California, Berkeley, have developed a new microscale actuator which could find its application in novel microfluidics, drug delivery, and artificial muscles. The actuators are smaller than the width of a human hair and are based on an oxide material… »
