Scientists have designed a 3D-printed “bionic” eye they claim could help restore sight in blind people.A team of researchers at the University of Minnesota in the US says it has, for the first time, created a prototype eye with built-in light receptors. Dr Michael McAlpine, a co-author of the study and an associate professor of mechanical engineering at the university, said: “Bionic eyes are usually thought of as science fiction, but now we are closer than ever using a multi-material 3D printer.” The light receptors, or photodiodes, are made up of semiconducting polymer materials and convert light into electricity.They are fitted on a hemispherical glass dome that makes up the structure of the eye, which is coated with a base ink made up of silver particles. According to the team, it takes about an hour to print the eye.The prototype is a long way away from being used in humans but Dr McAlpine said the team was “surprised” by the “25% … [Read more...] about Could 3D-printed bionic eyes let blind people see again?
Researchers have used 3D printing technologies to create light receptors on a hemispherical surface which could pave the way for future bionic eyes.On Tuesday, academics from the US University of Minnesota said the invention is a "significant step" towards the creation of synthetic eyes which could either restore sight for the blind or improve levels of sight for the visually impaired.3D printing on straight, flat surfaces is common, but attempting to print delicate components reliably on curved surfaces represents a challenge. The team began their journey with a hemispherical glass dome, which approximates the spherical surface of organic eyes.CNET: Bionic hand with sense of touch can be worn outside the labUsing a custom 3D printer designed for the task, the scientists were able to print a base ink of silver particles onto the dome. The silver ink dried in place, leading to the printing of an additional layer of materials through semiconducting polymers. The semiconducting … [Read more...] about 3D printed bionic eye prototype could one day restore sight
In case you haven’t noticed, Apple is slowly but surely pushing augmented reality into the mainstream. But if you’re wondering how Apple can make the jump from something like the iPhone X to a pair of smart glasses, this GIF nails how that evolution could take place: This GIF was a concept made by Leonardo Pazmatos, which he uploaded to the 3D-sketching “uMake” app for iPad. As you can tell from the GIF, Pazmatos uses the same TrueDepth camera system from the iPhone X – with its front-facing camera and sensors to capture 3D information – to serve as the foundation for Apple’s augmented-reality (AR) smart glasses. Augmented reality, for those unfamiliar, lets you see virtual images in the real world. As Paul Canetti put it so well, AR is like “photoshopping the whole world.” So if you look at the GIF, putting the TrueDepth camera system on the front of a pair of smart glasses would make a great deal of sense, … [Read more...] about This GIF nails how the iPhone X could be the foundation for Apple’s rumored smart glasses
By Roger Fingas Thursday, April 26, 2018, 06:10 am PT (09:10 am ET) Images claimed to be first real-world photos of the "iPhone SE 2" may suggest that Apple is bringing some touches of the iPhone 8 to the device, but not all of them. Most noticeable is the switch to a glass back, which could hint that Apple is planning to implement wireless charging —though the change might also be cosmetic. The photos were spotted on China's Weibo by Czech site Letemsvetem. The phone in other ways mostly resembles the current-generation iPhone SE, including its surrounding metal band, and a rear camera that sits flush with the body. The latter may imply that camera technology won't be on par with what's in the iPhone 8 line. Also still present are a Touch ID sensor and a 3.5-millimeter headphone jack. Continued use of Touch ID is expected —given the cost and complexity of the TrueDepth camera for Face ID —but removing the headphone jack would presumably open up internal design … [Read more...] about Alleged ‘iPhone SE 2’ with glass back & headphone jack spotted in new pictures
Open Bionics is a UK-based company, devoted to creating affordable, robotic prosthetics. Today they’re launching the “Hero Arm” – a 3D-printed, medically approved bionic arm that was designed to “turn disabilities into superpowers.” It is a lightweight, robotic prosthetic device with a customizable look, and it was built specifically for people (aged eight and older) lacking a limb below the elbows. From “How did you get that arm” to “Where did you get that arm” The Hero Arm was announced approximately a month ago. Today, you can apply for a robotic limb of your own through the company’s website. Each bionic arm is personally made to fit its particular owner. It boasts specs of being lightweight, yet strong (able to lift up to eight kilos), having long-lasting battery life, and excellent fine motor skills, as you can see in this video of a girl using her Hero Arm to pick up tiny marbles. The arm is also supposed … [Read more...] about Open Bionic’s prosthetic Hero Arm is now available in the UK
