Researchers have developed an electronic glove or e-gloves that can be worn over a prosthetic hand to provide human-like softness, warmth, appearance and sensory perception, such as the ability to sense pressure, temperature and hydration.

The e-glove uses thin, flexible electronic sensors and miniaturized silicon-based circuit chips on the commercially available nitrile glove.

The e-glove is connected to a specially designed wristwatch, allowing for real-time display of sensory data and remote transmission to the user for post-data processing, said the team from Purdue University.

“We developed a novel concept of the soft-packaged, sensor-instrumented e-glove built on a commercial nitrile glove, allowing it to seamlessly fit on arbitrary hand shapes,” said Chi Hwan Lee, Assistant Professor in Purdue’s College of Engineering.

The e-glove is configured with a stretchable form of multimodal sensors to collect various information such as pressure, temperature, humidity and electrophysiological biosignals, while simultaneously providing realistic human hand-like softness, appearance and even warmth.

Lee and his team hope that the appearance and capabilities of the e-glove will improve the well-being of prosthetic hand users by allowing them to feel more comfortable in social contexts.

The glove is available in different skin tone colors, has lifelike fingerprints and artificial fingernails.

“The prospective end user could be any prosthetic hand users who have felt uncomfortable wearing current prosthetic hands, especially in many social contexts,” Lee added in a paper published in the journal NPG Asia Materials.

The team is also seeking partners to collaborate in clinical trials or experts in the prosthetics field to validate the use of the e-glove and to continue optimizing the design of the glove. (IANS)

SpaceX Plans To Send NASA Astronauts To Space in Q2 This Year

As part of the test on Sunday, SpaceX configured Crew Dragon to trigger a launch escape about 1.5 minutes after liftoff

After NASA and SpaceX successfully completed a launch escape demonstration of the company’s Crew Dragon spacecraft and Falcon 9 rocket, Elon Musk said that his aerospace company aims to send NASA astronauts to space between April and June this year.

This was the final major flight test of the spacecraft before it begins carrying astronauts to the International Space Station (ISS) under NASA’s Commercial Crew Programme, the US space agency said in a statement on Sunday.

With this test now complete, the next big flight of the Crew Dragon will have people on board: NASA astronauts Bob Behnken and Doug Hurley.

“We’re highly confident that the hardware will be ready in Q1, most likely at the end of February but no later than March. And we think it appears probable that the first crewed launch would occur in the second quarter,” said Musk after the successful uncrewed test of its Crew Dragon capsule’s in-flight launch escape capabilities.

Musk said that if all goes well, the first crewed flight on the Crew Dragon could take place in the second quarter of this year.

“This critical flight test puts us on the cusp of returning the capability to launch astronauts in American spacecraft on American rockets from American soil,” said NASA Administrator Jim Bridenstine. “We are thrilled with the progress NASA’s Commercial Crew Programme is making and look forward to the next milestone for Crew Dragon.”

As part of the test on Sunday, SpaceX configured Crew Dragon to trigger a launch escape about 1.5 minutes after liftoff. All major functions were executed, including separation, engine firings, parachute deployment and landing. Crew Dragon splashed down at 10:38 am just off the Florida coast in the Atlantic Ocean.

“As far as we can tell thus far, it’s a picture perfect mission. It went as well as one can possibly expect,” said Musk. “This is a reflection of the dedication and hard work of the SpaceX and NASA teams to achieve this goal. Obviously, I’m super fired up. This is great.”

Prior to the flight test, teams completed launch day procedures for the first crewed flight test, from suit-up to launch pad operations. The joint teams now will begin the full data reviews that need to be completed prior to NASA astronauts flying the system during SpaceX’s Demo-2 mission. “The past few days have been an incredible experience for us,” said astronaut Doug Hurley.

“Today, we watched the demonstration of a system that we hope to never use, but can save lives if we ever do. It took a lot of work between NASA and SpaceX to get to this point, and we can’t wait to take a ride to the space station soon,” he said in the NASA statement. (IANS)
