Publication number: 20170054069Abstract: This invention provides kilometer-long, endlessly parallel, spontaneously piezoelectric and thermally stable poly(vinylidene fluoride) (PVDF) ribbons using iterative size reduction technique based on thermal fiber drawing method. The PVDF ribbons are thermally stable and conserve the polar ? phase even after being exposed to heat treatment above the melting point of PVDF. A single PVDF ribbon has an average effective piezoelectric constant as ?58.5 pm/V. PVDF ribbons in the invention are promising structures for constructing devices such as highly efficient energy generators, large area pressure sensors, artificial muscle and skin, due to the unique geometry and extended lengths, high polar phase content, high thermal stability and high piezoelectric coefficient.Type: ApplicationFiled: August 18, 2015Publication date: February 23, 2017Inventor: Mehmet Bayindir

Patent number: 8098966Abstract: There is provided a thermal sensing fiber grid, including a plurality of rows and columns of thermal sensing fibers, each of which includes a semiconducting element that has a fiber length and that is characterized by a bandgap energy corresponding to a selected operational temperature range of the fiber in which there can be produced a change in thermally-excited electronic charge carrier population in the semiconducting element in response to a temperature change in the selected temperature range. There is included at least one pair of conducting electrodes in contact with the semiconducting element along the fiber length, and an insulator along the fiber length. An electronic circuit is provided for and connected to each thermal sensing fiber for producing an indication of thermal sensing fiber grid coordinates of a change in ambient temperature.Type: GrantFiled: June 18, 2010Date of Patent: January 17, 2012Assignee: Massachusetts Institute of TechnologyInventors: Mehmet Bayindir, Fabien Soren, Ayman F.

Patent number: 7292758Abstract: The invention provides an optical fiber photodetector including a photoconductive element, such as a semiconducting element, having a fiber length. The semiconducting element is characterized as a non-composite material in at least one fiber direction. At least one pair of conducting electrodes is in contact with the semiconducting element along the fiber length, and an insulator is provided along the fiber length. An optical resonator can be disposed along the fiber length and along a path of illumination to the semiconducting element.
