An apparatus including a first ferrule, a second ferrule and a tracing fiber. The first ferrule may comprise a cap. The second ferrule may comprise the cap. The tracing fiber may be configured to propagate light from the first ferrule to the second ferrule. The first ferrule may enable the light to be directed into the tracing fiber when the cap is removed. The cap of the second ferrule may be configured to scatter the light to provide an omnidirectional emission of the light from the second ferrule. The tracing fiber may be bundled with one or more data carrying lines in a cable. Each of the data carrying lines may be configured to enable a communication of data. The tracing fiber may be configured to propagate the light without interrupting the communication of data.

A high-voltage electrical cable assembly includes a central wire strand containing at least seven wires formed of a first alloy and a plurality of outer wire strands twisted around the central strand. At least one outer wire strand of the plurality of outer wire strands contains at least seven wires formed of a second alloy different from the first alloy. There is an electrochemical potential of about 2 volts between the first alloy and the second alloy. A method of assembling a high-voltage electrical cable assembly is also presented herein.

An implantable medical device includes an electrode and an insulative material secured to the electrode via an adhesive. The electrode includes a metal substrate and a metal coating. The metal substrate includes a connection segment and an active segment along a length of the metal substrate. The metal coating is disposed on an outer surface of the metal substrate along the connection segment and the active segment. The insulative material surrounds the connection segment of the metal substrate without surrounding the active segment, and the adhesive adheres to the metal coating on the connection segment.

The present disclosure relates to a silver powder preparation method comprising: a silver powder preparation step of preparing a silver salt, which comprises silver ions, and then reducing the silver ion so as to precipitate silver particles; a silver powder recovery step of separating silver particles from an aqueous solution or a slurry, which comprises the precipitated silver particles, and then washing and drying same to recover silver powder; and a silver powder coating step of injecting a pH adjuster into the recovered silver powder to adjust the pH, and then injecting a coating agent to coat after the pH adjustment. The pH adjuster is used in the silver powder coating step to adjust the pH, and thus, when silver power is used in a conductive paste, as the rate of change in viscosity over time is low, a conductive paste having excellent viscosity stability can be provided.

The sheath (3) is a material, which includes an aluminium (Al) matrix, in which nanometric aluminium oxide particles (Al.sub.2O.sub.3) are homogenously dispersed, the content of Al.sub.2O.sub.3 is 0.25 to 5 vol. % and the balance is Al. It is preferred that Al.sub.2O.sub.3 originates from the surface layer present on Al powder used as feedstock material for consolidation. The superconductor based on magnesium diboride (MgB.sub.2) core (1) is fabricated by powder-in-tube or internal magnesium diffusion to boron technology, while the tube is the Al+Al.sub.2O.sub.3 composite, which is a product of powder metallurgy. A loose Al powder is pressed by cold isostatic pressing, and then the powder billet is degassed at elevated temperature and under vacuum, and then is hot extruded into a tube. A thin diffusion barrier (2) tube filled up with a mixture of Mg and B powders or Mg wire surrounded with B powder is placed into the Al+Al.sub.2O.sub.3 composite tube under inert gas or vacuum. Such composite unit is cold worked into a thin wire and then annealed at 625-655° C. for 8-90 min, what results in a formation superconducting MgB.sub.2 in a wire's core (1).

A cable includes: core wires comprising a pair of inner conductors and an inner insulating layer separately covered around each of the pair of inner conductors; a wrapping layer covering the core wires; a shielding layer covering the wrapping layer; and an outer coating layer covering the shielding layer; wherein the wrapping layer comprises a first wrapping layer covering the core wires and a second wrapping layer covering the first wrapping layer.

A soft sensor includes an elastic sheet, which includes a first elastic layer and a second elastic layer facing each other, and a sensor unit formed by printing a predetermined conductive liquid metal between the first elastic layer and the second elastic layer. A hand-wearable device may include at least one soft sensor, wherein the hand-wearable device has a shape corresponding to at least a portion of a shape of a hand, and the soft sensor is located at a position corresponding to at least some joints of the hand.
