  • Patent number: 10260533
    Abstract: A modular pneumatic robotic actuator, including a first elongated hollow structure and a second elongated hollow structure connected to each other at a moveable joint; an inflatable bladder comprised of an elastomeric material disposed at the said joint and immobilized between the first and second hollow structures, wherein the said inflatable bladder inflates preferentially away from the joint; and a restraining membrane comprised of an elastomeric material disposed over the bladder and connecting the first and second hollow structures, wherein the said restraining membrane is relaxed when the bladder is deflated.
    Type: Grant
    Filed: August 1, 2017
    Date of Patent: April 16, 2019
    Assignee: President and Fellows of Harvard College

  • Patent number: 10190970
    Abstract: The present invention relates to a sensor using a tilted fiber grating to detect physical manifestations occurring in a medium. Such physical manifestations induce measurable changes in the optical property of the tilted fiber grating. The sensor comprises a sensing surface which is to be exposed to the medium, an optical pathway and a tilted grating in the optical pathway. The grating is responsive to electromagnetic radiation propagating in the optical pathway to generate a response conveying information on the physical manifestation.
