Soft robotic assistive gripping device
ActiveUS20180361596A1Easy to controlEasy to removeProgramme-controlled manipulatorGripping headsDiseaseEngineering
This invention is directed to offer a customizable, cost effective, and comfortable soft gripping solution for patients with chronic disabilities, such as diabetic neuropathy, allowing the patients to function independently and perform routine daily tasks. A soft robotic gripper has been developed with one or more inflatable systems actuated by aft to assist a user to grip an object. The main body of the gripper bends with air actuation while the fingertip actuation helps functionality in the extremities. The gripper is further enhanced by adding sensors that integrate feedback for sensitivity to touch, conformability, and grip ability. The modular design modifications allow for gripper adjustments as the disease progresses or rescinds. The gripper also works as a training aid for routine physical therapy exercises. Data collected by a microprocessor can also help learn more about these chronic diseases and use artificial intelligence to customize treatment regimens for individual patients.

With applications such as soft robotics being severely hindered by the lack of strong soft actuators, the invention provides a new soft-actuator material—Electrically Actuated Hydraulic Solid (EAHS) material—with a stress-density that outperforms any known electrically-actuatable material. One type of actuator is fabricated by making a closed cell that acts as highly paralyzed version of a standard paraffin actuator. Each cell exhibits microscopic expansion, which is summed to produce macroscopic motion. The closed cellular nature of the material allows the system to be cut and punctured and still operate. It can be produced in a lab or industrial scale, and can be formed using molding, 3D printing or cutting.
