Abstract: Devices and methods for encapsulating a portion of a wound dressing with biocompatible coating are disclosed. In some embodiments, a method includes coating a first side of a flexible wound contact layer of the wound dressing with a hydrophobic coating. The first side of the wound contact layer can support a plurality of electronic components. The method can further include coating a second side of the wound contact layer opposite the first side with the hydrophobic coating. The wound contact layer can be formed at least partially from hydrophilic material.

Abstract: In some cases, a wound dressing and a method for coating a wound dressing is provided. A first coating may be applied on a first side of a substantially flexible substrate of the wound dressing. The first side of the substrate may support a plurality of electronic components, electronic tracks, and a plurality of connectors between the electronic components and electronic tracks. The first coating may be applied to at least one connector of the plurality of connectors or to at least one electronic components of the plurality of electronic components to reinforce the at least one connector or the at least one electronic components.

Abstract: A monitoring and/or therapy apparatus can include a contact layer having a stretchable or substantially stretchable substrate, at least one strain sensor coupled with the contact layer, and electronic circuitry electronically coupled with the at least one strain sensor configured to determine an amount of an elongation of the at least one strain sensor based on a change in a resistance or capacitance of the at least one strain sensor. The at least one strain sensor can include a plurality of stretchable tracks positioned on the substrate, and can be configured such that the resistance of the at least one strain sensor increases as the contact layer is elongated and/ or curved. In some arrangements, the apparatus and/or the substrate can be attached to or adjacent to a user’s joint, and/or a wound, and can be configured to have reduced pressure applied to the space under the contact layer..

Abstract: Methods of manufacturing a wound monitoring and/or therapy apparatus and/or wound dressing include positioning electronic components and connections in regions of a substrate that are not configured to be perforated. The methods can also include following a set of rules for positioning the components as well as positioning and shaping the connections based on the constraints stemming from, among other things, the positioning of the perforations on the substrate and with the goal of maintaining acceptable levels of signal integrity. The methods further include manufacturing a multi-layered substrate. Wound monitoring and/or therapy apparatus manufactured using such methods are also disclosed.

Abstract: In some cases, a wound dressing includes a substantially flexible substrate with a first, wound-facing side supporting a plurality of electronic components and a second side opposite the first side, a wicking layer in contact with the second side of the substrate, the wicking layer configured to facilitate passage of fluid, a substantially non-stretchable coating applied to at least some of the plurality of electronic components, a substantially stretchable coating applied to the first side of the substrate, the stretchable coating applied over the substantially non-stretchable coating, a wound contact layer in contact with the stretchable coating, the wound contact layer configured to adhere to a wound, and a protective layer applied to the wound contact layer, the protective layer configured to be removed to expose the wound contact layer. In some cases, a method of manufacturing the wound dressing.

Abstract: A wound treatment apparatus can include a wound dressing configured to be positioned proximate to a wound. Multiple optical fibers positioned at least partly in the wound dressing can include a first optical fiber and a second optical fiber. The wound treatment apparatus can include an emitter and a detector. The emitter can emit first electromagnetic radiation into the first optical fiber so that the first optical fiber passes the first electromagnetic radiation. The detector can generate a signal responsive to second electromagnetic radiation that exits the second optical fiber and contacts the detector.

Abstract: An activity-monitoring device for positioning on a body of a user or on an orthopedic device is provided. The device has a housing that encloses a circuit board assembly having a sensor that monitors movement of the circuit board assembly. The housing may be secured to the body of a user or orthopedic device with an dressing. The dressing can include a film layer to which the housing is adhered by an adhesive. The dressing can include a contact layer that is configured to attach to the user or to an orthopedic device.

Abstract: In some embodiments, a wound therapy apparatus includes a wound dressing configured to be positioned over a wound, the wound dressing including a substantially stretchable wound contact layer supporting a plurality of electronic components and a plurality of electronic connections that connect at least some of the plurality of the electronic components. The wound contact layer can include a first plurality of flocked fibers positioned on a wound facing side of the wound contact layer, the first plurality of flocked fibers including soft material configured to cushion the wound contact layer when the wound dressing is positioned over the wound. The wound contact layer can include a second plurality of flocked fibers positioned on a non-wound facing side opposite the wound facing side.
