3M Provides High-Volume Touch Sensor
Touch screen sensor material.
San Diego, CA — 3M Touch Systems, Inc. has introduced commercial MicroTouch Flex Capacitive Touch Sensors, a polyester-based projected capacitive touch screen solution especially suitable for high-volume mobile display products, such as cell phones, PDAs, MP3 players, and personal navigation systems.

The MicroTouch Flex Capacitive Touch Sensor is uniquely manufactured in a roll-to-roll process by applying a variety of patent-pending Indium Tin Oxide (ITO) patterns on lightweight, cost-effective polyester film (PET).

The result is an incredibly thin, optically clear projected capacitive touch sensor available to device manufacturers in rolls containing up to 72,000 sensors, depending on size. The roll configuration provides manufacturers with optimal scalability for fluctuating product volumes and production flexibility for changes in product design, component stack-ups and compact integration requirements.

Easily customized into a variety of shapes and sizes, the product can also be designed for touch applications ranging from simple button operation to full X-Y touch screen capabilities. Various material thicknesses are available to meet compact design requirements, currently ranging from 2mil to 5mil in thickness. These ultrathin touch sensors can be optically laminated to glass or polycarbonate lens for optimal surface durability with touch sensitivity "projected" through the lens. Or, by using hard coated polyester, these sensors can work directly as lightweight touch screens for devices requiring a more economical and thinner touch profile.
