In an embodiment, a syringe needle comprises a helical portion located in between a needle tip portion and a distal portion. In another embodiment, a compliant article comprises a casing tube comprising a tube end opening located at a needle tube end of the casing tube, a distal tube opening located at a distal tube end of the casing tube, and an inner tube space; and a syringe needle that traverses the tube end opening; wherein the compliant article comprises a compliant portion that allows for a reduced insertion pressure of the syringe needle as compared to an insertion pressure of a corresponding syringe needle in an article without the compliant portion.

Compliant syringe system, a method of making, and of using the same

The invention provides novel devices, systems, designs, materials and fabrication methods that enable high-load capacity, easy release, and suitable for extended/repeated use in a variety of applications.

High capacity easy release extended use adhesive devices

The invention provides unique releasable adhesive devices that are high-load bearing and highly stable while allowing adjustment of the weight-bearing angle in a wide range, thereby greatly expanding the scope of applications for technology. Adhesive systems and devices of the invention can be designed to fit applications ranging from household weight-bearing shelves and holders, components for transportation, athletic equipment, labels and advertising posts, automobile interior trims, permanent or reversible fasteners, as well as instruments and devices for industrial, commercial, medical or military applications.

Weight-bearing adhesives with adjustable angles

The invention provides unique releasable adhesive devices and related methods that are capable of simultaneously adhering to two or multiple target surfaces of various nature and allow high load capacity, are reusable, easy release and suitable for extended and repeated use.

Double- and multi-sided adhesive devices

Unique designs, devices, systems, materials and fabrication methods are provided including adhesive closure devices that are easily released and are suitable for extended/repeated use in a variety of applications.

High capacity easy release extended use adhesive closure devices

Gecko-like adhesive application devices suited for dynamic applications are disclosed, where the device can be easily applied to target substrates, exhibiting a firm hold, and subsequently released therefrom. Gecko-like adhesive application devices that are suited for sustained holding after easy application (e.g., on vertical or inclined surfaces or ceiling) also are disclosed.

Devices for application and load bearing and method of using the same

The invention provides highly resilient synthetic hydrogels, which can be prepared, for example, by using the efficient thiol-norbornene chemistry to cross-link hydrophilic poly(ethylene glycol) (PEG) and hydrophobic polydimethylsiloxane (PDMS) polymer chains. The simple hydrogel system with enhanced mechanical properties is useful in many applications, including in the biomedical field and in the design of protective and corrective wear.

Stimuli-responsive surfaces and related methods of fabrication and use

A wrinkled adhesive surface is prepared by swelling a laterally confined elastomer layer with a polymerizable monomer composition. Swelling the elastomer layer spontaneously produces a wrinkled surface, and the wrinkles are then stabilized by polymerizing the polymerizable monomer composition. The stabilized wrinkled surfaces prepare by the method can exhibit substantially enhanced adhesion relative to smooth surfaces of the same material. The stabilized wrinkled surfaces can also exhibit adhesion that is repeatable through many cycles of contact with and separation from another surface. The adhesive characteristics of the stabilized wrinkled surfaces can be tailored by manipulating the size of the wrinkles.

Wrinkled adhesive surfaces and methods for the preparation thereof

A method of forming a polymer film includes dispensing a substrate and coating the substrate with a composition that is curable using actinic radiation. In an example, the method further includes exposing the composition to actinic radiation in presence of an atmosphere including 1 vol % to 37 vol % oxygen, whereby the surface of the composition forms an undulating morphology. In another example, the method further includes applying an oxygen-containing overlay over the composition, exposing the composition to actinic radiation through the oxygen-containing overlay, and removing the oxygen-containing overlay, whereby the surface of the composition forms an undulating morphology.
