Patent number: 11759634Abstract: In illustrative implementations of this invention, interferential stimulation is precisely directed to arbitrary regions in a brain. The target region is not limited to the area immediately beneath the electrodes, but may be any superficial, mid-depth or deep brain structure. Targeting is achieved by positioning the region of maximum envelope amplitude so that it is located at the targeted tissue. Leakage between current channels is greatly reduced by making at least one of the current channels anti-phasic: that is, the electrode pair of at least one of the current channels has a phase difference between the two electrodes that is substantially equal to 180 degrees. Pairs of stimulating electrodes are positioned side-by-side, rather than in a conventional crisscross pattern, and thus produce only one region of maximum envelope amplitude. Typically, current sources are used to drive the interferential currents.Type: GrantFiled: January 1, 2021Date of Patent: September 19, 2023Assignee: Massachusetts Institute of TechnologyInventors: Nir Grossman, David Bono, Edward Boyden

Publication number: 20070282378Abstract: Apparatus and method for harvesting energy from the environment and/or other external sources and converting it to useful electrical energy. The harvester does not contain a permanent magnet or other local field source but instead relies on the earth's magnetic field of another source of a magnetic field that is external to the sensing device. One advantage of these new harvesters is that they can be made smaller and lighter than energy harvesters that contain a magnet and/or an inertial mass. A small implantable stimulator(s) includes at least one passive magnetostrictive/electro-active (PME) magnetic-field sensor for delivering electrical stimulation to surrounding tissue. The PME is charged utilizing a changing magnetic field from an external alternating magnetic field source at a frequency particular to the PME. The small stimulator provides means of stimulating a nerve, tissue or internal organ with direct electrical current, such as relatively low-level direct current for temporary or as needed therapy.Type: ApplicationFiled: April 11, 2007Publication date: December 6, 2007Applicant: FERRO SOLUTIONS, INC.Inventors: Jiankang Huang, Hariharan Sundram, Robert O'Handley, David Bono

Patent number: 6984902Abstract: In a vibrational energy harvester, an external vibration causes relative motion between a permanent magnet and a magnetic field sensing element composed of a magnetostrictive material bonded to an electroactive material. The changing magnetic field causes a rotation of magnetization in the magnetostrictive material and the rotating magnetization generates a stress in the magnetostrictive material. The stress is transmitted to the electroactive material, which responds by generating electrical power.Type: GrantFiled: January 29, 2004Date of Patent: January 10, 2006Assignee: Ferro Solutions, Inc.Inventors: Jiankang Huang, Robert C.
