Publication number: 20220143408Abstract: Breast reconstruction and/or mastectomy may be performed to treat or prevent breast cancer or for a variety of other purposes. These procedures can result in disruption of the innervation of the breast, leading to loss of sensation. This loss of sensation can lead to diminishment of sexual function, sexual dysfunction, or other undesired effects. To restore the lost sensory function, an implanted system is provided. The system includes a sensor configured to detect one or more of pressure, stain, or vibration. The detected input is used to determine a stimulus, and the stimulus is provided to one or more of the intercostal nerves to restore sensation.Type: ApplicationFiled: January 31, 2020Publication date: May 12, 2022Inventors: Stacy Tessler Lindau, Sliman Bensmaia, Gillian Feldmeth, Katie Long, Sihong Wang

Patent number: 11118150Abstract: A layered, microfluidic array is disclosed. The array has a first layer with a culture channels extending in a first longitudinal direction. Each culture channel includes multiple traps that entrap cell or tissue samples. The array also has a second layer with microfluidic channels extending in a second longitudinal direction that is orthogonal the first longitudinal direction. A third layer, disposed between the first layer and the second layer, has pores arranged within the third layer such that each nest is vertically stacked above, and fluidly connected with, a corresponding culture chamber in the first layer. Each nest is fluidly isolated from adjacent nests by a fluid impermeable region of the third layer such that horizontal diffusion of water within the third layer is prevented.Type: GrantFiled: January 10, 2019Date of Patent: September 14, 2021Assignees: Research Foundation of the City University of New York, Memorial Sloan Kettering Cancer CenterInventors: Sihong Wang, A.

Patent number: 10367431Abstract: A triboelectric generator includes a first contact charging member and a second contact charging member. The first contact charging member includes a first contact layer and a conductive electrode layer. The first contact layer includes a material that has a triboelectric series rating indicating a propensity to gain electrons due to a contacting event. The conductive electrode layer is disposed along the back side of the contact layer. The second contact charging member is spaced apart from and disposed oppositely from the first contact charging member. It includes an electrically conductive material layer that has a triboelectric series rating indicating a propensity to lose electrons when contacted by the first contact layer during the contacting event. The electrically conductive material acts as an electrode. A mechanism maintains a space between the first contact charging member and the second contact charging member except when a force is applied thereto.Type: GrantFiled: March 13, 2017Date of Patent: July 30, 2019Assignee: Georgia Tech Research CorporationInventors: Zhong Lin Wang, Sihong Wang, Long Lin, Guang Zhu, Zong-Hong Lin

Patent number: 9985554Abstract: A generator includes a first member, a second member and a sliding mechanism. The first member includes a first electrode and a first dielectric layer affixed to the first electrode. The first dielectric layer includes a first material that has a first rating on a triboelectric series. The second member includes a second material that has a second rating on the triboelectric series that is different from the first rating. The second member includes a second electrode. The second member is disposed adjacent to the first dielectric layer so that the first dielectric layer is disposed between the first electrode and the second electrode. The sliding mechanism is configured to cause relative lateral movement between the first member and the second member, thereby generating an electric potential imbalance between the first electrode and the second electrode.Type: GrantFiled: February 25, 2014Date of Patent: May 29, 2018Assignee: Georgia Tech Research CorporationInventors: Zhong Lin Wang, Guang Zhu, Sihong Wang, Long Lin
