Circe: Transforming greenhouse gases into biodegradable products
Our society is built upon cheap, widely available petrochemicals. Beyond gasoline and other fuels, petrochemicals are primary components of many of the objects in our everyday lives, including clothing, cosmetics, electronics, packaging, paint, floors, cars, and furniture. The vast majority of these products do not biodegrade in the environment and are not recycled, and the... -
MM3D: Multimaterial Multinozzle 3D Printing
3D printers are revolutionizing manufacturing by allowing users to create any physical shape they can imagine on-demand. However, most extrusion-based printers available commercially are only able to build objects from a single nozzle at a time. Those that can deposit multiple inks are even slower due to the additional time required to switch between materials.... -
Single-Cell Encapsulation for Improved Cell Therapies
Mesenchymal stromal cells (MSCs) are valued for their ability to secrete compounds that modulate the body’s immune system, making them an attractive solution for existing problems with cell therapies including host-vs-graft disease and organ transplant rejections. However, MSCs are rapidly cleared from the body and can come under fire from the immune system. Efforts to... -
Smart Tools: RFID Tracking for Surgical Instruments
Surgeons can use up to 250 different tools during a surgical procedure to perform tasks like cutting, grasping, cauterizing, suturing, suctioning, and reducing bleeding. Each tool must be manually counted by hospital staff both before and after surgery to ensure that none of them have gone missing, which is a tedious and time-consuming process. This... -
FOAMs: Soft Robotic Artificial Muscles
Soft robots, similar to living organisms, are made from compliant materials that allow them great flexibility and adaptability for tasks at the human-robot interface and elsewhere. To enable soft robotic missions in different industrial, exploratory, and medical settings, engineers are trying to equip them with artificial muscles that could enable them to move smoothly, efficiently... -
DNA Data Storage
The genetic material DNA has garnered considerable interest as a medium for digital information storage because its density and durability are superior to those of existing silicon-based storage media. For example, DNA is at least 1000-fold more dense than the most compact solid-state hard drive and at least 300-fold more durable than the most stable...

Video/AnimationVoxelated Soft Matter via Multimaterial, Multinozzle 3D PrintingMultimaterial Multinozzle 3D (MM3D) Printing, a new technique developed by engineers at the Wyss Institute and Harvard SEAS, allows seamless switching between up to eight different materials within a single nozzle, allowing for the creation of complex 3D objects in a fraction of the time required by other extrusion-based 3D printing methods.

Audio/PodcastDisruptive: 3D BioprintingThere are roughly 120,000 people in the United States on waiting lists for live-saving organ transplants, with only about 30,000 transplants happening every year. To address this great challenge of organ shortages, a team at the Wyss Institute led by Core Faculty member Jennifer Lewis, Sc.D., is developing a method for 3D bioprinting organ tissues... -
Video/AnimationA Swifter Way Towards 3D-printed Organs20 people die waiting for an organ transplant every day in the US, but lab-grown organs so far lack the cellular density and functions required to make them viable replacements. The new SWIFT method from the Wyss Institute and Harvard SEAS solves those problems by 3D printing vascular channel networks directly into living tissue constructs,... -
Video/AnimationHip-only Soft Exosuit for both Walking and RunningThis video demonstrates the use of the hip-assisting exosuit in different natural environments, and shows how the robotic device senses changes in the gait-specific vertical movements of the center of mass during walking and running to rapidly adjust its actuation.

Video/AnimationSelf-regenerating bacterial hydrogels as intestinal wound patchesThis animation explains how self-regenerating bacterial hydrogels could be used as adhesive patches to help intestinal wounds heal. Credit: Wyss Institute at Harvard University. -
Video/AnimationTension PistonsThe Tension Piston, developed at the Wyss Institute and MIT CSAIL, amplifies piston force and increases energy efficiency by using flexible materials to transmit fluid-induced tension. The Tension Piston is able to produce substantially greater force compared to a conventional piston at the same driving pressure. Tension Pistons can be used in pumps, engines, compressors,...
