Device-Specific MEMS

Numerous MEMS-based devices have been  designed, tested, and evaluated by Southwest Research Institute (SwRI) engineers. MEMS devices use integrated circuit fabrication techniques to create extremely small devices, from 1 micron to 1 mm in length.

SwRI MEMS Development Capabilities

• Electrostatic actuators

• Thermal actuators

• Microfluidics/Bio-MEMS

• Optical components

• Mechanical property testing

• Interaction with non-MEMS materials

SwRI engineers developed a bidirectional horizontal thermal actuator that can be used to exert force in two directions. (U.S. Patent No. 6,607,714)

MEMS Services

	SwRI engineers developed this stress corrosion cracking sensor. A test beam made of the relevant structural material can electrically detect crack growth in situ or be used as a life prediction tool. U.S. Patent #6,925,888.

• Concept development

• Fundamental and finite element analysis

• Mask design layout services

• Fabrication coordination

• Wet-etch release

• Wire bonding and packaging

• System design and integration

MEMS System Integration

SwRI engineers can integrate your MEMS device into a finished hand-held or desktop device. We understand the complexities of handling MEMS devices in an uncontrolled environment and can design your finished product to withstand the "real world" interface.

SwRI engineers can add product functionality in the following areas:

• Optics

• Wireless communication

• Low-noise analog electronics

• Digital signal processing

• Software development

• Embedded systems

• Mechanical design and fabrication

• Ergonomics

• Product packaging

• Design transfer to manufacturing
