Low-Cost Tactile Displays for the Blind and Visually Impaired
Age-related medical conditions are responsible for most cases of blindness and visual impairment worldwide. In 2015, there were an estimated 36 million blind people in the world, with an additional 217 million suffering from moderate to severe vision impairment. Over 80% of the visually impaired were older than 50, and this percentage is expected to... -
EverActive: Strength Tracking Sensor for Sustainable Personalized Training
Exercise is key to good health, where aerobic and strength training are the two essential types. Industry has developed a number of aids and appliances ranging from sports watches to large stationary equipment to help track aerobic activities. Meanwhile, people still have to record manually their strength workouts and only few can do it, as... -
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.... -
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... -
milliDelta: Millimeter-Scale Delta Robot
Delta robots are deployed in many industrial processes, including pick-and-place assemblies, machining, welding, and food packaging. Three individually controlled lightweight arms enable fast and accurate motion of an output platform in three directions. Roboticists have reduced the size of Delta robots for tasks in limited workspaces, but so far, using conventional manufacturing techniques and components,... -
HAMR: Versatile Crawling Microrobot
Small or difficult-to-access spaces such as areas covered with rubble, or narrow pipes and engines can pose obstacles to search-and-rescue missions, repair works, or environmental and industrial monitoring. One solution for these problems could be small-sized robots that are able to navigate such spaces, transport payload, sense, and communicate. Wyss Institute researchers have developed a...

Video/AnimationSmart Thermally Actuating TextilesSmart Thermally Actuating Textiles (STATs) are tightly-sealed pouches that are able to change shape or maintain their pressure even in environments in which the exterior temperature or airflow fluctuates. This soft robotics technology could be developed as novel components of rehabilitation therapies or to prevent tissue damage in hospital bed or wheelchair-bound individuals. Credit: Wyss... -
Video/AnimationSoft Robotic Gripper for Jellyfish 2.0Scientists from the Wyss Institute at Harvard University and CUNY have created ultra-soft robotic grippers that resemble fettuccini noodles to safely catch and release delicate underwater creatures like jellyfish without harm.

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,...
