E-Skin Can Pick Up Eggs

1 Making Artificial Skin from Nanowires

Engineers in California are working on making artificial skin from nanowires. The electronic skin (or e-skin), which would function like real human skin, would have the ability to feel and touch objects, even delicately enough to pick up an egg. "This is the first truly macroscale integration of ordered nanowire materials for a functional system, in this case, an electronic skin," said Kuniharu Takei, study lead author and post-doctoral fellow in electrical engineering and computer sciences. For the artificial skin, UC Berkeley engineers have utilized a fabrication technique similar to a lint roller in reverse. Rather than picking up fibers, the technique allows for deposit of nanowire "hairs." The technology may one day be useful for restoring sense of touch in patients with prosthetics.

Killer Caribbean Mosquitoes

2 Record Dengue Deaths in Puerto Rico

The Centers for Disease Control and Prevention (CDC) issued a statement on Friday about the increasing number of dengue deaths in the U.S. Caribbean territory Puerto Rico this year. A record 20 people in Puerto Rico have died from dengue. According to MSNBC, several Caribbean islands have declared a dengue epidemic. CDC officials are also investigating additional deaths which may possibly be contributed to the virus, as well as 11,600 more suspected cases. Dengue, which is transmitted by mosquitoes, can turn into a more serious illness known as hemorrhagic dengue. CDC has confirmed 28 cases of hemorrhagic dengue, which may cause death from shock. Dengue was responsible for 19 deaths and 17,000 illnesses in 1998.

Heads-Up for Basketball

3 Basketball-Related Traumatic Brain Injuries Rising

Basketball-related traumatic brain injuries (TBIs) among children and adolescents between the ages of 5 and 19 rose 70 percent from 1997 to 2007, say researchers from the Center for Injury Research and Policy at Nationwide Children's Hospital. The study examined basketball-related injuries treated in emergency rooms. Findings, which appear in Pediatrics, reveal that the proportion of TBIs tripled for girls and doubled for boys during the 11-year study period. Researchers also found that the most common injuries in kids' basketball are sprains and strains to the lower extremities, and fractures or dislocations to the upper extremities. Study co-author Lara McKenzie, PhD says that using age-appropriate basketballs helps decrease rates of finger injuries and concussions.

The Future of Skin

4 Artificial Skin Synthesized in the Lab

Researchers have created electronic skin that can sense touch, hoping to improve the next generation of robots and prosthetic limbs. The bottom layer is a matrix of nanonwires made of germanium and silicon that are rolled on a stick polyimide file with nanoscale transistors on top. On top of that a pressure-sensitive rubber. This “e-skin” detects pressures that reflect typing a keyboard, for example. Another team used a rubber film that responds to pressure by changing its thickness and incorporates capacitors in the material to measure the changes, but it cannot be stretched. Challenges that remain are creating artificial skin that detects more complex sensations which means connecting it to the nervous system and make it respond to other stimuli such as climate and chemicals.
