inkjet_printerChemical engineers led by Dr. Woo Lee at Stevens Institute of Technology have made strides in the advancement of printed electronics. The researchers have developed an innovative method of applying graphene to inkjet printing technology. The process involves the development of graphene “ink,” which is conductive, strong, transparent, and can store energy, to create graphene electrodes for use in printed electronics. This technology may someday make the manufacture of paper-thin personal electronics such as mp3 players and smart phones possible. Graphene-based inkjet printing can also be applied in the medical field to “print” agents that combat infections onto orthopedic implants to improve surgical success rates.

Biomedical engineers at Case Western Reserve University have developed a method to engineer cartilage which could be used to replace that which is found in parts of the body such as the knee, ear, and nose. The process, which uses a patient’s own stem cells to drive cartilage formation, resulted in tougher cartilage than in previous attempts. The engineered cartilage shared many similarities to articulate cartilage (the type of cartilage found in the knee), but it did not quite measure up to the real thing. The researchers are working on optimizing their process to create cartilage tough enough to stand up to the rigors of everyday life.

An anti-icing system for airport runways is being developed by engineering researchers at the University of Arkansas. The design employs an overlay of conductive concrete panels atop the runway. A photovoltaic system supplies energy to embedded electrodes within the panels to maintain temperatures above freezing and prevent the accumulation of snow and ice. The system, which is currently in the testing phase, will have the potential to make runways safer and less costly to maintain during the winter months.

German researchers have developed a robotic rescue spider which could be used to explore dangerous areas after a disaster such as an earthquake. The robotic spider was produced so inexpensively using a 3D printer that it is literally disposable. The robot is programmed to move just like a real spider and some models can even jump. In the event of a disaster, the spider could provide responders with valuable information such as photos or air quality data from the disaster zone.

The Institution of Mechanical Engineers (IME) in London†is developing geo-engineering technology that can absorb detrimental carbon dioxide emissions from the atmosphere. Resembling fields of giant fly-swatters, the air capture devices are a thousand times more effective at absorbing CO2 than similarly-sized trees, which could help counter global warming. After being captured, the CO2 can then be used in industry or stored safely underground. It is anticipated that the technology will be ready to be rolled out in the UK by 2018. Learn more…

Irish student Alexander Amini, won top honors in the engineering category at the†23rdwoman_playing_tennis European Union Contest for Young Scientists. Amini developed a sensor system to track speed, orientation, and†13 different stroke types with over 95% accuracy. In addition to sports, the system has applications in both emergency medicine and physical therapy.††

Engineers at the University of Utah have developed a system which can accurately monitor patients’ breathing without the need for connection to wires. The engineers placed 20 wireless tranceivers around the perimeter of a bed, sending crisscrossing signals on a patient lying in the bed. The breathing motion of the patient’s chest and abdomen impeded the intersecting signals, which were then translated into breathing rate. The system can capture 380 individual measurements of patients’ breathing and is as accurate as wired systems. The network has the potential for use with†post-surgical patients, patients with sleep apnea, and infants at risk for SIDS.
