摘要： An apparatus for in-situ sensing of longitudinal and transverse strain in biological tissue (e.g. tendons and ligaments) includes a set of sensing electrodes that contact biological tissue and enable measurement of an electrical property of the biological tissue along two or more directions. The apparatus may also include a sensing module that senses the electrical property of the biological tissue along the two or more directions to provide multi-directional measurements that are captured by a logging module. The apparatus may also include a transmission module that transmits the captured measurements to a data analysis workstation or the like. The data analysis workstation may include a strain estimation module that receives the multi-directional measurement and estimates a longitudinal strain and a transverse strain therefrom. A corresponding system and method for in-situ sensing of longitudinal and transverse strain in biological tissue is also presented.

摘要： In one general aspect, an apparatus comprises a material including a non-layered mixture of an elastomeric polymer with a plurality of voids; and a plurality of conductive fillers disposed in the elastomeric polymer. The apparatus may produce an electrical response to deformation and, thus, function as a strain gauge. The conductive fillers may include conductive nanoparticles and/or conductive stabilizers. In another general aspect, a method of measuring compression strain includes detecting, along a first axis, an electrical response generated in response to an impact to a uniform composite material that includes conductive fillers and voids disposed throughout an elastomeric polymer, and determining a deformation of the impact based on the electrical response. The impact may be along a second axis different from the first axis.

摘要： A multi-stage stent including a stent body and a bio-erodible material is provided. The stent body can be compressed in an initial state and the bio-erodible material can be coupled to the stent body in a configuration that holds the stent body in an expanded first state, following a first stage expansion from the initial state upon deployment of the stent body. Upon erosion of the bio-erodible material the stent body is released from the first state to expand further in a second stage expansion to a second state.
