SENSORS :: Specifications and Materials for Medical Sensors cont'd.

Printing - CT prints using large-format, screen-printing presses, both hand-feed and automated, that accept sheeted materials. Substrates are registered using edge alignment. Automated presses use optical detection for registration. Inks can be cured either by UV or heat.

Reagent Deposition - Reagent can be applied using several techniques including microdeposition from a positive-displacement pump or printing. Environmentally-controlled rooms for applications that require high or low humidity are available. Reagents are cured in low-temperature ovens.

Assembly - CT has experience in laminating plastic materials using pressure-sensitive and heat-sealable adhesives. Adhesives can be applied as sheet goods or they can be printed depending on the application. Embossing or die cutting to form structures is also available. Cutting can be performed using lasers, optically-aligned presses, non-assisted punch presses, and slitting.

Packaging - CT can work with its customers to develop and implement packaging solutions. Final excision of sensors from cards or coupons can be accomplished using laser cutting, die cutting or slitting. Finished sensors are typically packaged in bottle formats. For applications where cards or large sensors are to be supplied, vacuum-seal packaging is available.
