Abstract:
For solar cell fabrication, the addition of precursors to printable media to assist etching through silicon nitride or silicon oxide layer thus affording contact with the substance underneath the nitride or oxide layer. The etching mechanism may be by molten ceramics formed in situ, fluoride-based etching, as well as a combination of the two.
Abstract:
A breathable electrical heater element for a topical application device such as a wound dressing or a therapeutic heating pad is disclosed. The heater element is formed by photochemically etching a track pattern onto a porous metallised fabric (e.g. nickel coated woven polyester). The heater element has a skin or wound contact layer laminated to the front face of the heater element. An adhesive layer is laminated to the back face of the heater element. The adhesive layer forms an overhang to provide an adhesive border around the wound contact layer to adhere the device to the skin of a patient. Therapeutically active drugs (optionally microencapsulated) may be incorporated into the skin or wound contact layer. Operation of the heater element causes the skin or wound contact layer to release the active drugs to the skin or wound of the patient. Appropriate control of the temperature of the heater element allows control of the release of the active drugs.
Abstract:
Disclosed is a breathable heater element for a garment or for the lining of a garment such as an outdoor jacket, e.g. a waterproof jacket. The heater element is formed from porous metallised fabric such a nickel plated woven polyester fabric by photochemical etching of a suitable track pattern onto the metallised fabric. The formed heater element is then laminated into a lining. The material of the lining may be impregnated with microencapsulated functional chemicals such as fragrances, perfumes, antimicrobials or insect repellents. The microcapsules release their contents on activation due to heat generated by the heater element.

Abstract:
Disclosed is a breathable insole heater element (12, 40) for footwear. The heater element is formed by photochemically etching a porous metallised fabric, e.g. nickel-metallised polyester woven fabric. The heater element is embedded in or laminated in an insole for an article of footwear such as a shoe or boot. The insole may be cut to size as desired. The insole may include microencapsulated agents such as fragrances, perfumes, microbials or insect repellents. The microcapsules may be activated to release the agents due to the heat generated by the heater element in operation.
Abstract:
A flexible electric circuit, for example an electric heater, comprises a metallised fabric (14) the metal of which is photochemically etched to form the circuit (16), the fabric preferably being porous.
Abstract:
The present invention provides for a suture comprising a flexible foraminous cover made of a polymeric material, and a core within the cover made of a cushioning material. The cover material is preferably formed of uhmw polyethylene, nylon or polypropylene. The cushioning material is preferably polyester, PTFE or nylon. Preferably, the core is twisted at about 1.5 turns per inch and comprises about 22% of the suture.
