|LOS ANGELES adidas superstar rainbow black , May 13 (Xinhua) -- U.S. researchers have developeda "revolutionary" process for 3D printing stretchable electronicsensory devices that could give robots the ability to feel theirenvironment.
The discovery, published online in the journal AdvancedMaterials, is a major step forward in printing electronics on realhuman skin, researchers say.
The new process was developed by engineers at the University ofMinnesota using a one-of-a-kind 3D printer they built in thelab.
The multifunctional printer is equipped with four nozzles, toprint different kinds of specialized "ink" that make up the layersof the device.
These flexible 3D printed sensors can stretch up to three timestheir original size, according to the study.
"This stretchable electronic fabric we developed has manypractical uses adidas superstar rainbow white ," Michael McAlpine, a University of Minnesotamechanical engineering associate professor and lead researcher onthe study, said in a statement.
"Putting this type of 'bionic skin' on surgical robots wouldgive surgeons the ability to actually feel during minimallyinvasive surgeries, which would make surgery easier instead of justusing cameras like they do now. These sensors could also make iteasier for other robots to walk and interact with theirenvironment."
Researchers believe the new 3D printing technique could also beused to print electronics directly on real human skin. Thisultimate wearable technology may could eventually be used forhealth monitoring or by soldiers in the field to detect dangerouschemicals or explosives.
Conventional 3D printing using liquid plastic is too hot and toorigid to use on the skin. However, all the layers of "ink" used inthis new technique can set at room temperature, making for"endless" possible applications.
"This is a completely new way to approach 3D printing ofelectronics adidas superstar rainbow paint splatter ," McAlpine said. "This could take us into so manydirections from health monitoring to energy harvesting to chemicalsensing." Enditem
RIO DE JANEIRO, April 17 (Xinhua) -- Brazil's meat processing companies, JBS and BRF, among the largest in the world, have seen 5.4 billion reais (1.74 billion U.S. dollars) wiped off their value over the last month, owing to the ongoing adulterated meat scandal adidas superstar pride pack for sale , a study revealed on Monday.
The data, released by the consultancy Economatica, showed that JBS, the largest global producer of animal protein, had lost 15.35 percent of its total value since the scandal broke on March 17. It slumped from being worth 32.6 billion reais (10.52 billion dollars) on March 16 to 27.6 billion reais (8.9 billion dollars) last week.
BRF suffered less, losing just 1.45 percent of its value adidas nmd chukka grey , dropping to 31.5 billion reais (10.17 billion dollars) over the same period.
The two multinationals are accused of chemically altering meat to mask its smell and change its color as well as selling expired meat products.
Brazil's federal police have charged 63 people for participating in these activities.
All have been charged with passive corruption, use of forbidden or illicit substances, falsification of medical records, adulteration of food products or substances, embezzlement, malversation adidas nmd chukka black suede , and use of false documentation, among others.
The revelation of the case led to at least 25 countries imposing restrictions on imports and purchases of Brazilian meat, although most have since been lifted after the Brazilian government led a campaign to show it only concerns a small portion of its meat industry.
Brazil is the largest global exporter of beef and chicken and the fourth-largest exporter of pork. However, the government has calculated that the scandal could cost 10 percent of its external market, leading to a loss of around 1.5 billion dollars a year.

FRANKFURT, May 1 (Xinhua) -- Two persons were slightly injured in the train derailment Monday evening in Dortmund, a city in Germany's state of North Rhine-Westphalia, said the federal police of the state via twitter.
The accident happened shortly before 7 p.m. when the high-speed train ICE 945 from Dusseldorf to Berlin was arriving at the Dortmund Central Railway Station. The last three of the seven carriages of the train jumped out of the tenth track of the railway station, the police said via twitter.
All the passengers on board have been evacuated and one of the injured has been sent to local hospital for treatment, the other got treatment at the railway station.
The train and track bed were seriously damaged adidas nmd human race blue , and the cause of the accident remains unknown, said the police.
