May 5, 2003 — Applied MEMS Inc. of Houston will manufacture its MEMS Si-Flex accelerometer for Refraction Technology Inc., a maker of seismic recording systems for earthquake monitoring, according to a news release.
The sensor converts ground vibrations into an electronic signal. The MEMS sensors are better than conventional seismic monitoring technology because they are smaller, weigh less and are less vulnerable to electromagnetic interference, among other advantages, according to an Applied MEMS engineer quoted in the release. Applied MEMS is a subsidiary of Input/Output Inc.
