Multimaterial 3D Printing Manufactures Complex Objects, Fast
A new technique called multimaterial multinozzle 3D printing uses high-speed pressure valves to achieve rapid, continuous, and seamless switching between up to eight different printing materials, enabling the creation of complex shapes in a fraction of the time currently required using printheads that range from a single nozzle to large multinozzle arrays.
Sensor Could be Used for Microrobotics, Augmented Reality, Wearables
For all our technological advances, nothing beats evolution when it comes to research and development. Take jumping spiders. These small arachnids have impressive depth perception despite their tiny brains, allowing them to accurately pounce on unsuspecting targets from several body lengths away.
A swifter way towards 3D-printed organs
Sacrificial ink-writing technique allows 3D printing of large, vascularized human organ building blocks.
Self-folding "Rollbot" paves the way for fully untethered soft robots
The majority of soft robots today rely on external power and control, keeping them tethered to off-board systems or rigged with hard components. Now, researchers have developed soft robotic systems, inspired by origami, that can move and change shape in response to external stimuli, paving the way for fully untethered soft robots.
Exosuit shows potential for wearable robots
Researchers have previously developed robotic devices for rehabilitation and other areas of life that can either assist walking or running, but no untethered portable device could efficiently do both.
Snake-inspired robot slithers even better
Bad news for ophiophobes: Researchers have developed a new and improved snake-inspired soft robot that is faster and more precise than its predecessor.
Artificial muscles for soft robots
Developing soft, artificial muscles that are also fast and strong is an important step in developing soft robots that can both safely interact with people and complete important tasks.
A safe, wearable soft sensor
Children born prematurely often develop neuromotor and cognitive developmental disabilities. The best way to reduce the impacts of those disabilities is to catch them early through a series of cognitive and motor tests. But accurately measuring and recording the motor functions of small children is tricky.
Robots with sticky feet
Jet engines can have up to 25,000 individual parts, making regular maintenance a tedious task that can take over a month per engine. Many components are located deep inside the engine and cannot be inspected without taking the machine apart, adding time and costs to maintenance. This problem is not only confined to jet engines, either; many complicated, expensive machines.
A painless adhesive for bandaids
Pulling off a Band-Aid may soon get a lot less painful. Researchers have developed a new type of adhesive that can strongly adhere wet materials -- such as hydrogel and living tissue -- and be easily detached with a specific frequency of light.
Personalized soft exosuit breaks new ground
Fully wearable soft exosuit with automatic tuning helps users save energy and walk outside over difficult terrain.
Printing with sound
Harvard University researchers have developed a new printing method that uses sound waves to generate droplets from liquids with an unprecedented range of composition and viscosity. This technique could finally enable the manufacturing of many new biopharmaceuticals, cosmetics, and food and expand the possibilities of optical and conductive materials.
Soft multifunctional robots get really small
Robots could be safely deployed in difficult-to-access environments, such as in delicate surgical procedures in the human body.
Gentle robotic hand for sea life
The open ocean is the largest and least explored environment on Earth, estimated to hold up to a million species that have yet to be described. However, many of those organisms are soft-bodied - like jellyfish, squid, and octopuses - and are difficult to capture for study with existing underwater tools, which all too frequently damage or destroy them. Now, a new device safely traps delicate sea creatures inside a folding polyhedral enclosure and lets them go without harm using a novel, origami-inspired design.
Robotic cockroach can explore underwater environments
In nature, cockroaches can survive underwater for up to 30 minutes. Now, a robotic cockroach can do even better. Harvard's Ambulatory Microrobot, known as HAMR, can walk on land, swim on the surface of water, and walk underwater for as long as necessary, opening up new environments for this little bot to explore.
3D printing method embeds sensing capabilities in robotic actuators
Soft robots that can sense touch, pressure, movement and temperature.
Breakthroughs seen in artificial eye and muscle technology
Inspired by the human eye, researchers have developed an adaptive metalens that is essentially a flat, electronically controlled artificial eye. The adaptive metalens simultaneously controls for three of the major contributors to blurry images: focus, astigmatism, and image shift.
Snake-inspired robot uses kirigami to move
Who needs legs? With their sleek bodies, snakes can slither up to 14 miles-per-hour, squeeze into tight space, scale trees and swim. How do they do it? It's all in the scales.
Rotational 3D printing technique yields high-performance composites
Nature has produced exquisite composite materials—wood, bone, teeth, and shells, for example—that combine light weight and density with desirable mechanical properties such as stiffness, strength and damage tolerance.
