Snake-Inspired Robot Slithers Even Better Than Predecessor
Bad news for ophiophobes: Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a new and improved snake-inspired soft robot that is faster and more precise than its predecessor. The robot is made using kirigami — a Japanese paper craft that relies on cuts to change the properties…
Adhesives for Biomedical Applications Can be Detached With Light
Pulling off a Band-Aid may soon get a lot less painful. Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and Xi’an Jiaotong University in China have developed a new type of adhesive that can strongly adhere wet materials — such as hydrogel and living tissue — and be easily…
Next-Generation Robotic Cockroach can Explore Under Water 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. This next…
‘Breakthrough’ Algorithm Exponentially Faster Than Any Previous One
Squeezing Light at the Nanoscale—Ultra-Confined Light Could Detect Harmful Molecules
Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a new technique to squeeze infrared light into ultra-confined spaces, generating an intense, nanoscale antenna that could be used to detect single biomolecules. The researchers harnessed the power of polaritons, particles that blur the distinction between light and matter.…
Tunable Diamond String may Hold Key to Quantum Memory
A quantum internet promises completely secure communication. But using quantum bits or qubits to carry information requires a radically new piece of hardware – a quantum memory. This atomic-scale device needs to store quantum information and convert it into light to transmit across the network. A major challenge to this vision is that qubits are…
Nanofiber Dressings Soothe Wounds and Encourage Regeneration
Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and the Wyss Institute for Biologically Inspired Engineering have developed new wound dressings that dramatically accelerate healing and improve tissue regeneration. The two different types of nanofiber dressings, described in separate papers, use naturally-occurring proteins in plants and animals to promote…
Drawing Inspiration From Plants and Animals to Restore Tissue
Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and the Wyss Institute for Biologically Inspired Engineering have developed new wound dressings that dramatically accelerate healing and improve tissue regeneration. The two different types of nanofiber dressings, described in separate papers, use naturally-occurring proteins in plants and animals to promote…
Artificial Eye: Researchers Combine Metalens with an Artificial Muscle
Inspired by the human eye, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) 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. The research is…
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. As a snake moves, its scales grip the ground and propel the body forward – similar to how crampons help hikers establish footholds…

Novel 3D Printing Technique Yields High-Performance Composites
Researchers Demonstrate High-Quality Optical Microstructures Using Lithium Niobate
If the epicenter of the electronics revolution is named after the material that made it possible — silicon?– then the birthplace of the photonics revolution may well be named after lithium niobate. While Lithium Niobate Valley doesn’t have the same ring as Silicon Valley, this material could be for optics what silicon was for electronics.…
Bridging the Terahertz Gap
Optical frequency combs are widely-used, high-precision tools for measuring and detecting different frequencies — a.k.a. colors — of light. Unlike conventional lasers, which emit a single frequency, these lasers emit multiple frequencies simultaneously. The equally spaced frequencies resemble the teeth of a comb. Optical frequency combs are used for everything from measuring the fingerprints of…

Smaller, Smarter, Softer, Robotic Arm for Endoscopic Surgery
Flexible endoscopes can snake through narrow passages to treat difficult to reach areas of the body. However, once they arrive at their target, these devices rely on rigid surgical tools to manipulate or remove tissue. These tools offer surgeons reduced dexterity and sensing, limiting the current therapeutic capabilities of the endoscope. Now, researchers from the…
Safely Releasing Genetically Modified Genes into the Wild
So, you’ve genetically engineered a malaria-resistant mosquito, now what? How many mosquitos would you need to replace the disease-carrying wild type? What is the most effective distribution pattern? How could you stop a premature release of the engineered mosquitos? Releasing genetically engineered organisms into an environment without knowing the answers to these questions could cause…
Soft Robot Helps The Heart Beat
Harvard University and Boston Children’s Hospital researchers have developed a customizable soft robot that fits around a heart and helps it beat, potentially opening new treatment options for people suffering from heart failure. The soft robotic sleeve twists and compresses in synch with a beating heart, augmenting cardiovascular functions weakened by heart failure. Unlike currently…
Paving the Way Toward Strong, Conductive Materials
Action figures of the Man of Steel are rarely made out of steel. They are, like seemingly everything in our lives, made of cheap, easy to mold plastic. But what if steel and other metals were as easy to work with as plastic? Bulk metallic glasses are metallic alloys whose neatly ordered atomic structure can…
Artificial Muscle for Soft Robotics: Low Voltage, High Hopes
Soft robots do a lot of things well but they’re not exactly known for their speed. The artificial muscles that move soft robots, called actuators, tend to rely on hydraulics or pneumatics, which are slow to respond and difficult to store. Dielectric elastomers, soft materials that have good insulating properties, could offer an alternative to…
