SCHOTT FLEXINITY™ for sensoring applications

Pressure Sensors

High quality and durable pressure sensors require materials with very specific properties. Glass and silicon share one important property: their coefficient of thermal expansion. When joined through anodic bonding, glass and silicon react to temperature changes in the same way, minimizing stresses throughout the bonding interface. Additionally, the surface roughness has to be extremely low, since adhesion strongly depends on surface quality.

As devices, modules and sensors tend to become thinner and lighter, glass substrates need to be as thin as possible to fit seamlessly.

SCHOTT’s structured wafers feature fire-polished surface quality to permit strong bonding, and are available in wafers thinner than a human hair, perfect for use as ultra-small sensors.

SCHOTT FLEXINITY™ for microfluidic applications

Microfluidics

D 263^{^®} bio is easy to structure and can be toughened chemically, making it an ideal choice for applications that need uncompromising optical quality and very high chemical resistance. It can be used as a substrate glass for optical diagnostics, microfluidic components or other consumer and industrial applications.
