Soft electronics are an emerging class of electronic devices that are flexible and stretchable, designed to move with the body. A team from Harvard’s Wyss Institute and Harvard SEAS has developed a new 3D printing platform that integrates hard and soft electronic elements into durable, stretchable sensors and enables rapid design and manufacturing of soft electronics.This is achieved by first printing a stretchable conductive ink. As the printed ink is stretched, its electrical resistivity increases. Next, surface mounted electrical components are digitally pick-and-placed in precise locations.Because the soft matrix and conductive electrodes are 3D-printed, researchers have complete control over where the electronic features are placed. The printed wearable sensor and integrated electronic device is mounted on a stretchable textile fabric.This platform rapidly accelerates the design and additive manufacturing of customized, wearable electronic devices.

Marine fouling occurs when organisms attach themselves to underwater objects like boats, rope, pipes and building structures. Mussels are one of the biggest culprits. Once attached, they are difficult to remove, leading to operational downtime, increased energy use and damage. Paints and coatings are currently used to prevent marine fouling, but are frequently toxin-based and not very effective, with adverse environmental and economic impact.Researchers are Harvard's Wyss Institute and Harvard SEAS have developed non-toxic, lubricant-infused, slippery surface coatings. Their collaborators at Nanyang Technological University in Singapore, showed that these surfaces interfered with the Asian green mussels' (Perna viridis) ability to adhere to solid surfaces. The research team also tested their slippery coatings at the NOAA Stellwagen Bank National Marine Sanctuary in Scituate, MA. The marine sanctuary field site is home to the blue mussel (Mytilus edulis) and a variety of other biofouling organisms, all of which seemed to be repelled by the coating. The team is continuing to test their surfaces at different field sites around the world. This slippery surface coating technology has many potential applications in maritime industries.For more information, please visit: wyss.harvard.edu/slippery-liquid-surfaces-confuse-mussels-to-stop-them-from-sticking-to-underwater-structures/

Building upon previous soft exosuit technology, researchers at the Wyss Institute and Harvard SEAS have developed a soft exosuit for running. This exosuit applies forces to the hip joint using thin, flexible wires, assisting the muscles during each stride. Using an off-board actuation system, compared to not wearing the exosuit, this exosuit can reduce the metabolic cost of running by 5.4%.

Wyss Core Faculty, Dave Mooney, explains our new Immuno-Materials focus area which adds a new dimension to immunotherapy in that it harnesses materials to make treatments more efficient and effective. These material-based systems are capable of modulating immune cells and releasing them into the body where they can treat diseases.

It is well known that as plants grow, their stems and shoots respond to outside signals like light and gravity. But if plants all have similar stimuli, why are there so many different plant shapes? Using simple mathematical ideas, Harvard University researchers constructed a framework that explains and quantifies the different shapes of plant stems. Credit: Harvard SEAS

Project Abbie is inspired by the story of Abbie Benford, who succumbed to complications related to anaphylaxis just eight days before her 16th birthday. The Wyss Institute, in collaboration with Boston Children’s Hospital, is developing a wearable, non-invasive device that could sense anaphylaxis and automatically inject epinephrine in individuals who are unable to do so themselves; a device that could have saved Abbie’s life.

Printing vessel vasculature is essential for sustaining functional living tissues. Until now, bioengineers have had difficulty building thick tissues, lacking a method to embed vascular networks.A 3D bioprinting method invented at the Wyss Institute and Harvard SEAS embeds a grid of vasculature into thick tissue laden with human stem cells and connective matrix. Printed within a custom-made housing, this method can be used to create tissue of any shape.Once printed, an inlet and outlet own opposite ends are perfused with fluids, nutrients, and cell growth factors, which control stem cell differentiation and sustain cell functions. By flowing growth factors through the vasculature, stem cells can be differentiated into a variety of tissue cell types.This vascularized 3D printing process could open new doors to tissue replacement and engineering.Footage credit: David Kolesky, Lori Sanders, and Jennifer LewisFor more information, please visit: http://wyss.harvard.edu/viewpressrelease/250/

A team at the Wyss Institute and Harvard SEAS has developed a new microscale printing method to create transformable objects. These "4D-printed" objects go a step beyond 3D printing to incorporate a fourth dimension–time.The method was inspired by the way plants change shape over time in response to environmental stimuli. This orchid-shaped structure is printed with a hydrogel composite ink containing aligned cellulose fibrils, which enable anisotropic swelling. A proprietary mathematical model developed by the team precisely predicts how the fibrils will swell in water.After printing, the 4D orchid is immersed in water to activate its shape transformation.Credit: A.S.

Development of new therapeutics for chronic lung diseases have been hindered by the inability to study them in vitro. To address this challenge, Wyss Institute researchers used their Organ-on-a-Chip technology to produce a microfluidic 'human lung small airway-on-a-chip.'The device, which is composed a clear rubber material, is lined by living Human lung small airway cells on one side and capillary blood vessel cells on the other, much like in the living lung. In the device, air flows over the top of the human lung cells and liquid medium containing white blood cells flow below capillary cell layer. In the airway chip, the lung cells have hair-like cilia that move rhythmically, helping the mucus flow out of the lung chip, just as they do in the living lung.Wyss researchers also have been able to line the chip with diseased cells from COPD patients, and these chips retain the features of patients¹ lungs with this disease, including an increased ability to become inflamed when exposed to viral or bacterial pathogens. And when inflammation is triggered in the chip, white blood cells flowing in the blood channel are stimulated to adhere to inflamed capillary blood vessel wall, as they do in our bodies.Using this disease model, researchers have identified new lung disease biomarkers, and demonstrated that the model can be used to test for new drugs for COPD as well as asthma.For more information, please visit: wyss.harvard.edu/viewpressrelease/235/
