Micro-supercapacitors store energy directly inside a chip

Batteries are getting better at a steady pace, but the technology is far from perfect – they are still quite short-lived, and have real trouble delivering bursts of power. Now, researchers at Drexel and the Paul Sabatier universities have managed to embed mini supercapacitors directly inside a microchip to enable electronics that are even smaller, last longer, and have more power to feed on.Read More

3D-printed living tumors make a better model for cancer research

Medical research is only as good as the model, whether you’re using one animal to stand in for another, or creating in vitro replicas of tissue and organs. A research lab at Drexel University specializing in biofabrication recently used 3D printing to create models of tumor tissue that more closely replicate real tumors than traditional 2D tissue culture. Appropriating tools in this manner could lead to a better understanding of how tumors grow, and importantly, how they die. Read More

Ultrasound-emitting "band-aids" speed healing of venous ulcers

Venous ulcers are nasty things, often found on the lower extremities of elderly or inactive people. They occur when high blood pressure causes the skin adjacent to the affected veins to break down, leaving open wounds that take months or even years to heal. Standard treatments include compression bandages, infection control and standard wound dressings, although these approaches don’t work in all cases. Now, however, scientists are getting good results using band-aid-like patches that emit ultrasound into the ulcers. Read More

DRC-HUBO revealed for DARPA Robotics Challenge

The DARPA Robotics Challenge (DRC) has scheduled its first physical trial for late December, leaving competing teams less than six months to finish building and programming their robots. In case you're just tuning in, the DRC is a gauntlet of daunting tasks designed to test robots that may someday stand in for people as first responders. DARPA has just revealed the completed ATLAS humanoid, but there's still a half dozen others that remain somewhat mysterious. Now, Team DRC-HUBO is spilling the beans on its own humanoid robot.Read More

Drones

Drexel University giving UAVs a hand (and arms)

UAVs have proven very successful as surveillance, intelligence-gathering and mapping craft, but their ability to interact with the ground has been largely confined to launching missiles. Now, Drexel University in Philadelphia, Pennsylvania is planning to endow them with arms and hands to allow them to work on such tasks as repairing infrastructure and disaster recovery while hovering near the ground.Read More

Disco ball-like side mirror for cars eliminates blind spots, without the fish-eye effect

While there are already various anti-blind-spot automobile mirrors on the market, these all tend to incorporate a very curved surface that drastically distorts the appearance of objects seen in them – given that drivers use their mirrors to avoid getting in accidents, it’s kind of important that those mirrors show the surrounding traffic as it really is. That’s why Dr. Andrew Hicks, a mathematics professor at Philadelphia’s Drexel University, has created a side mirror that eliminates the blind spot, while causing almost no distortion.Read More

3D printed fossil replicas used to build robotic dinosaurs

Although it may seem that we know a great deal about dinosaurs, a lot of the knowledge is actually based on assumptions rather than hard facts. Often, scientists have to resort to guesswork. Some hypotheses can only be tested by manipulating a skeleton model, but that's quite a challenge if the bones you want to study belonged to an enormous animal. Also, size is not the only issue. Dinosaur fossils tend to be fragile, unique and valuable. That's why the researchers at Drexel University, who want to build precise robotic models of dinosaurs, decided to use 3D printing technology. Read More
