Patent number: 10527507Abstract: An elastic strain sensor can be incorporated into an artificial skin that can sense flexing by the underlying support structure of the skin to detect and track motion of the support structure. The unidirectional elastic strain sensor can be formed by filling two or more channels in an elastic substrate material with a conductive liquid. At the ends of the channels, a loop port connects the channels to form a serpentine channel. The channels extend along the direction of strain and the loop portions have sufficiently large cross-sectional area in the direction transverse to the direction of strain that the sensor is unidirectional. The resistance is measured at the ends of the serpentine channel and can be used to determine the strain on the sensor. Additional channels can be added to increase the sensitivity of the sensor. The sensors can be stacked on top of each other to increase the sensitivity of the sensor.Type: GrantFiled: November 27, 2017Date of Patent: January 7, 2020Assignee: President and Fellows of Harvard CollegeInventors: Robert J. Wood, Yong-Lae Park, Carmel S. Majidi, Bor-rong Chen, Leia Stirling, Conor James Walsh, Radhika Nagpal, Diana Young, Yigit Menguc

Publication number: 20150148728Abstract: An orthosis system includes an orthotic device adapted to be worn on the hand of a subject that includes at least one brace component coupled to one or more fingers of the hand and including at least one joint permitting movement of one or more fingers. One or more actuators can be connected to each joint to cause movement of the joint. A control unit can be provided to control each of the actuators to control the movements of each joint separately. The control unit can be operated by the subject or a clinician to facilitate everyday tasks or for treatment or therapy.Type: ApplicationFiled: September 10, 2012Publication date: May 28, 2015Applicants: CHILDREN'S MEDICAL CENTER CORPORATION, PRESIDENT AND FELLOWS OF HARVARD COLLEGEInventors: Hani M.

Publication number: 20140330159Abstract: Typical neurological examinations focus on qualitative and subjective assessments, including obtaining a patient history, assessing the patient's cognitive status, motor and sensory skills, and cranial nerve functionality. A quantitative assessment of neurological condition includes recording a subject performing a visuomotor task and processing the performance data to determine a level of complexity in the task activity and determine a complexity index. For a sample healthy population, a baseline level of complexity and baseline complexity index can be determined. A patient's complexity index can be compared to this baseline complexity index as an indication of disease or disability. A baseline complexity index can be determined for a patient at part of a health maintenance examination and used as the baseline complexity to detect disease or disability in the future based on lower complexity index values in future examinations.Type: ApplicationFiled: September 26, 2012Publication date: November 6, 2014Applicants: BETH ISRAEL DEACONESS MEDICAL CENTER, INC., PRESIDENT AND FELLOWS OF HARVARD COLLEGEInventors: Madalena Damasio Costa, Leia A.

Publication number: 20120238914Abstract: An actively controlled orthotic device includes active components that dynamically change the structural characteristics of the orthotic device according to the orientation and locomotion of the corresponding body part, or according to the changing needs of the subject over a period of use. Accordingly, the orthotic device can be effectively employed to provide locomotion assistance, gait rehabilitation, and gait training. Similarly, the orthotic device may be applied to the wrist, elbow, torso, or any other body part. The active components may be actuated to effectively transmit force to a body part, such as a limb, to assist with movement when desired. Additionally or alternatively, the active components may also be actuated to provide support of varying rigidity for the corresponding body part.Type: ApplicationFiled: January 13, 2012Publication date: September 20, 2012Applicants: President and Fellows of Harvard College, Massachusetts Institute of Technology, Trustees of Boston University, Children's Medical Center CorporationInventors: Eugene C.
