Dissertation student Jan Torgersen of Vienna University of Technology looks at a video screen with a microscope picture of nano-structures as he operates a newly developed 3D laser printer, in Vienna March 29, 2012. Torgersen and colleagues have set a new world speed record for creating 3D nano objects. The University team create their grain of sand-size structures in just four minutes, a fraction of the time that other items have previously been printed. Previously making complex large 3D structures would take hours or even days but with the newly developed 3D laser printer the scientists can speed that up by a factor of 500 or in some cases 1,000 times. The process called ?two-photon lithography? involves using a focused laser beam to harden liquid resin in order to create micro objects of solid polymer. The scientists said the technique could be developed to make small biomedical parts to be used by doctors.  Picture taken March 29.

New ‘electronic skin’ monitors and treats patients by itself

Researchers have developed a new “electronic skin” wearable device that tracks patient motion, reads medical diagnostic information, and even administers medicine automatically by releasing drugs into the skin.

The device is as thin as a temporary tattoo, and is the first of its kind to both monitor and treat patients, and could eventually be employed to help patients with mobility disorders like Parkinson’s disease or epilepsy, nature.com reports.

Stretchable nanomaterials engineered to detect temperature, motion, store data, use microheaters and administer drugs are layered with soft, flexible skin-like material to make a 4-centimeter long, 2-centimeter wide and 0.003-centimeter thick sticky patch.

“The novelty is really in the integration of the memory device,” Swiss Federal Institute of Technology engineer Stephanie Lacour said while commenting on the research team’s work.

Before the device can be deployed for widespread patient use engineers will have to design similarly small battery and data transmitter components. According to study co-author and University of Texas in Austin mechanical engineer Nanshu Lu, the technology required already exists, but has yet to be converted into a small, thin and flexible size like their electronic skin device.

“It’s a pretty complicated system to integrate onto a piece of tattoo material,” Lu said. “It’s still pretty far away.”
