3M’s “100-Patent Woman” Audrey Sherman Explains How She Did It

Adhesive constructions include a mammalian skin surface and an adhesive article in contact with the mammalian skin. The adhesive article includes a substrate and an adhesive layer. The adhesive layer in contact with the mammalian skin is a microstructured surface with channels. At least one channel extends to at least one boundary of the adhesive layer. The microstructured surface is a permanently microstructured surface, such that the channels in the surface of the adhesive layer permit transport of fluid.

Fluid-managing medical adhesive articles with microstructured surfaces

Dry electrodes are electrodes for attachment to human skin without skin preparation or the use of electrolyte gels. The electrode includes a substrate, electrically conductive particles with at least one point, in contact with the substrate, a supporting layer that envelopes the electrically conductive particles with points that protrude from the supporting layer, and an electrical connector. Some electrodes have an electrically conductive substrate, other electrodes have an electrically conductive supporting layer.

Dry electrodes

An optical device for sensing a presence of an analyte in a person includes a light source, an optical stack, and a reader. The light source emits a first light having a first wavelength. The optical stack is placed on the a skin of the person and includes a sensor material and an optical filter. The sensor material emits a second light having a second wavelength when irradiated with the first light. An optical property of the second light is sensitive to the presence of the analyte. The optical filter is disposed on the sensor material and includes at least ten microlayers. The optical filter has different first and second transmittances at the respective first and second wavelengths.

Optical stack, optical device and optical construction

Systems and methods for customizing medical tapes from a roll stock at customer use sites are provided. The system includes a tape converting machine where an adhesion modification mechanism is configured to modify adhesion properties of the tape from the roll stock, automatically or based on received customization instructions.

On-demand manufacturing for medical tapes

Absorbent medical articles include a first absorbent layer with a radio opaque element located on the surface of the first absorbent layer. The radio opaque element has at least one segment that is non-linear and has at least one vertex, the vertex defines an angle of at least 15° and less than 165°. The radio opaque element may be a continuous or discontinuous element. The absorbent medical article may include additional absorbent layers. The radio opaque element makes the absorbent medical article detectable if left inside a patient.

Medical articles with radio opaque patterns

Medical dressings including stiffening systems fixedly attached to backing layers are described herein along with methods of using the medical dressings. The stiffening system is fixedly secured to the backing to limit flexing and stretching of the backing layer. Typically, the medical dressing and stiffening system is applied over a medical device that is secured to skin. The stiffening system covers some of the medical device and also extends beyond the medical device. The stiffening system stabilizes the medical device over the skin.

Medical dressings with stiffening systems

The disclosed reinforced adhesive substrate includes a transparent, flexible, breathable backing with a reinforcing material having open areas to the substrate. The reinforcing material strengthen the breathable backing while maintaining transparency so that overall the substrate is transparent. A transparent adhesive substrate can allow the underlying surface to be visualized.

Reinforced adhesive substrate

Siloxane-based gel adhesives with improved shear holding power are prepared from curable compositions. The curable compositions include a siloxane fluid with a viscosity of at least 1,000,000 centiPoise, a siloxane-(meth)acrylate co-polymer, and siloxane tackifying resin. The curable compositions can contain an initiator or can be cured by e-beam radiation without an initiator. The siloxane-(meth)acrylate copolymer is the reaction product of a reaction mixture of an ethylenically unsaturated siloxane-containing macromer, an alkyl (meth)acrylate monomer; optionally a reinforcing monomer, and an initiator.

Siloxane-based gel adhesives and articles

Aspects of the present disclosure relate to a self-mating fastener that includes a backing having a first side, and a rail element protruding perpendicularly from the first side of the backing. The rail element extends in a longitudinal direction along the backing. The rail element has a base portion attached to the first side of the backing and a cap portion distal from the backing. The cap portion has a cap width that is greater than a width of the base portion and the cap portion overhangs the base portion on opposing sides. The self-mating fastener includes an electrically conductive contact element proximate to the rail element.

Crowd funding for innovation includes distributing a proposal with a description of a project idea, an amount of funds requested, and a time frame for raising the funds. Ownership of the project is transferred to an entity, which receives contributions from contributors and for each of the received contributions converts the contribution to a corresponding amount of virtual coin and adds the contribution to the funds. If the funding goal is complete within the time frame, the entity converts the coins to actual money and releases the money to the requestor. After completion of the project, the entity determines if the project is successful and can commercialize successful projects. For certain successful projects, the entity can also distribute funds to the contributors.

An optical device is disclosed and includes an optical sensor, a plurality of photosensitive pixels disposed on the optical sensor, a wavelength-selective optical filter in optical communication with the photosensitive pixels, and a plurality of spatially-variant written regions disposed in the optical filter, the written regions having a transmission spectrum and each of the written regions being larger than each of the pixels.

An optical element includes a porous layer with a network of a plurality of interconnected voids. The porous layer is optically diffusive to at least one wavelength of light when the network of interconnected voids is substantially free of fluid. The porous layer of the optical element undergoes a detectable optical change upon fluid ingress into the network or egress from the network of interconnected voids.

Porous fluid sensor

Layers of siloxane tackifying resins that do not contain siloxane fluids, gums or polymers act as adhesion promotion agents. Articles include a substrate layer, a non-tacky siloxane tackifying resin adhesion promotion layer disposed on the surface of the substrate layer, and a crosslinked siloxane layer in contact with the adhesion promotion layer. The crosslinked siloxane layer is not an adhesive layer. The adhesion of the crosslinked siloxane layer to the substrate is greater than the adhesion without the non-tacky siloxane tackifying adhesion promotion layer.

Siloxane tackifying resin layers as adhesion promotion agents

The present invention is an optically clear, curable adhesive including a polyvinylbutyral, a polyurethane (meth)acrylate, a (meth)acrylate monomer, and a photoinitiator. The polyvinylbutyral has a dynamic viscosity of between about 9 and about 13 mPa&#xb7;s and a polyvinyl alcohol weight percent of less than about 18%. The polyurethane (meth)acrylate includes the reaction product of a diol, at least one diisocyanate, and a hydroxyfunctional (meth)acrylate or an isocyanatofunctional (meth)acrylate. When the optically clear, curable adhesive is placed between two transparent substrates and made into a laminate, the laminate has a haze of less than about 6%, a transmission of greater than about 88%, and an optical clarity of greater than about 98% when cured. The optically clear, curable adhesive also has a peel adhesion of at least about 100 g/cm based on ASTM 3330 when cured.

High performance photocurable optically clear adhesive

Blend compositions include at least one polydiorganosiloxane polyoxamide copolymer, and at least 70% by weight of at least one silicone tackifying resin. The blend composition is non-tacky at room temperature up to a temperature of at least 100&#xb0; C. The polydiorganosiloxane polyoxamide copolymer can be a linear or branched copolymer. The blend compositions provide solid, non-powdery, and non-tacky delivery vehicles for silicone tackifying resin.
