New e-skin innovation gives robots and prosthetics an exceptional sense of touch

Robots and prosthetic devices may soon have a sense of touch equivalent to, or better than, the human skin with the Asynchronous Coded Electronic Skin (ACES), an artificial nervous system developed by a team of researchers at the National University of Singapore (NUS).

The new electronic skin system achieved ultra-high responsiveness and robustness to damage, and can be paired with any kind of sensor skin layers to function effectively as an electronic skin.

The innovation, achieved by Assistant Professor Benjamin Tee and his team from the Department of Materials Science and Engineering at the NUS Faculty of Engineering, was first reported in the prestigious scientific journal Science Robotics on 18 July 2019.

5 Ways the Moon Landing Changed Life on Earth

When Neil Armstrong took his first steps on the Moon 50 years ago, he famously said “that’s one small step for a man, one giant leap for mankind.” He was referring to the historic milestone of exploring beyond our own planet — but there’s also another way to think about that giant leap: the massive effort to develop technologies to safely reach, walk on the Moon and return home led to countless innovations that have improved life on Earth.

Armstrong took one small step on the lunar surface, but the Moon landing led to a giant leap forward in innovations for humanity.

Here are five examples of technology developed for the Apollo program that we’re still using today:

1. Food Safety Standards

As soon as we started planning to send astronauts into space, we faced the problem of what to feed them — and how to ensure the food was safe to eat. Can you imagine getting food poisoning on a spacecraft, hundreds of thousands of miles from home?

We teamed up with a familiar name in food production: the Pillsbury Company. The company soon realized that existing quality control methods were lacking. There was no way to be certain, without extensive testing that destroyed the sample, that the food was free of bacteria and toxins.

Pillsbury revamped its entire food-safety process, creating what became the Hazard Analysis and Critical Control Point system. Its aim was to prevent food safety problems from occurring, rather than catch them after the fact. They managed this by analyzing and controlling every link in the chain, from the raw materials to the processing equipment to the people handling the food.

Today, this is one of the space program’s most far-reaching spinoffs. Beyond keeping the astronaut food supply safe, the Hazard Analysis and Critical Point system has also been adopted around the world — and likely reduced the risk of bacteria and toxins in your local grocery store. 

2. Digital Controls for Air and Spacecraft

The Apollo spacecraft was revolutionary for many reasons. Did you know it was the first vehicle to be controlled by a digital computer? Instead of pushrods and cables that pilots manually adjusted to manipulate the spacecraft, Apollo’s computer sent signals to actuators at the flick of a switch.

Besides being physically lighter and less cumbersome, the switch to a digital control system enabled storing large quantities of data and programming maneuvers with complex software.

Before Apollo, there were no digital computers to control airplanes either. Working together with the Navy and Draper Laboratory, we adapted the Apollo digital flight computer to work on airplanes. Today, whatever airline you might be flying, the pilot is controlling it digitally, based on the technology first developed for the flight to the Moon.

3. Earthquake-ready Shock Absorbers

A shock absorber descended from Apollo-era dampers and computers saves lives by stabilizing buildings during earthquakes.

Apollo’s Saturn V rockets had to stay connected to the fueling tubes on the launchpad up to the very last second. That presented a challenge: how to safely move those tubes out of the way once liftoff began. Given how fast they were moving, how could we ensure they wouldn’t bounce back and smash into the vehicle?

We contracted with Taylor Devices, Inc. to develop dampers to cushion the shock, forcing the company to push conventional shock isolation technology to the limit.

Shortly after, we went back to the company for a hydraulics-based high-speed computer. For that challenge, the company came up with fluidic dampers—filled with compressible fluid—that worked even better. We later applied the same technology on the Space Shuttle’s launchpad.

The company has since adapted these fluidic dampers for buildings and bridges to help them survive earthquakes. Today, they are successfully protecting structures in some of the most quake-prone areas of the world, including Tokyo, San Francisco and Taiwan.

4. Insulation for Space

We’ve all seen runners draped in silvery “space blankets” at the end of marathons, but did you know the material, called radiant barrier insulation, was actually created for space?

Temperatures outside of Earth’s atmosphere can fluctuate widely, from hundreds of degrees below to hundreds above zero. To better protect our astronauts, during the Apollo program we invented a new kind of effective, lightweight insulation.

We developed a method of coating mylar with a thin layer of vaporized metal particles. The resulting material had the look and weight of thin cellophane packaging, but was extremely reflective—and pound-for-pound, better than anything else available.

Today the material is still used to protect astronauts, as well as sensitive electronics, in nearly all of our missions. But it has also found countless uses on the ground, from space blankets for athletes to energy-saving insulation for buildings. It also protects essential components of MRI machines used in medicine and much, much more.

5. Healthcare Monitors

Patients in hospitals are hooked up to sensors that send important health data to the nurse’s station and beyond — which means when an alarm goes off, the right people come running to help.

This technology saves lives every day. But before it reached the ICU, it was invented for something even more extraordinary: sending health data from space down to Earth.

When the Apollo astronauts flew to the Moon, they were hooked up to a system of sensors that sent real-time information on their blood pressure, body temperature, heart rate and more to a team on the ground.

The system was developed for us by Spacelabs Healthcare, which quickly adapted it for hospital monitoring. The company now has telemetric monitoring equipment in nearly every hospital around the world, and it is expanding further, so at-risk patients and their doctors can keep track of their health even outside the hospital.

Only a few people have ever walked on the Moon, but the benefits of the Apollo program for the rest of us continue to ripple widely.

In the years since, we have continued to create innovations that have saved lives, helped the environment, and advanced all kinds of technology.

Now we’re going forward to the Moon with the Artemis program and on to Mars — and building ever more cutting-edge technologies to get us there. As with the many spinoffs from the Apollo era, these innovations will transform our lives for generations to come.

Sandra Cassell embraced her 2-year-old son, Evan, as he climbed into her lap at Maisonneuve-Rosemont Hospital Thursday morning. He peered into her eyes and she stared back at him, smiling with the boundless love of a proud mother.

That simple exchange of glances would have been impossible almost a year ago. For the past 16 years, a rare eye disease — retinitis pigmentosa — slowly robbed the Lachine resident of her eyesight to the point where she needed a white cane to cross the street.

But on Feb. 8, a medical team at Maisonneuve-Rosemont Hospital succeeded in partially restoring Cassell’s vision by implanting a prosthesis in her left retina, turning it into a bionic eye. The four-hour operation, led by eye surgeon Flavio Rezende, represents a medical first in Quebec.

“I never thought I’d be able to see again,” the 42-year-old social worker said.

“But now I can see. I see light, I see contrasts of different things, in black, in white and grey. It’s like an ultrasound picture.”

“This innovative technology gives hope to people with vision loss caused by degenerative diseases of the retina,” he added. “We are proud to be part of this revolution.”

The bionic eye was developed by Second Sight of California. The

Argus II Retinal Prosthesis System requires a person with severe retinitis pigmentosa to wear special glasses with a camera on the bridge. The video images taken by the camera are processed by a smartphone-sized computer worn around the waist. The images are then transmitted wirelessly to the eye implant, which is a tiny electrode array that looks like a computer chip that is embedded in the retina.

The electrode array bypasses the dead cells of the retina for ones that are still active, and those cells convert the pulses into signals for the brain.

At a cost of $150,000, the prosthesis will not be made available for everyone with vision problems. Only those patients with profound retinal dystrophy (which includes retinitis pigmentosa) will be eligible for the implant.
