Miniature Voice Coil Actuator It’s not news that medical devices are continuing to shrink, but this smaller-is-better trend would be unthinkable without the development of components small enough to drive them. Contributing to the development of miniaturized components for such portable medical devices as patient-worn drug-dispensing units and surgical hand tools, BEI Kimco Magnetics has designed the Model LA05-05-000A—a miniature voice coil actuator (VCA) that the company claims is approximately 0.13 in. smaller than competing models.“The VCA represents a breakthrough for two reasons,” states Miguel Hermosillo, BEI Kimco’s applications engineer for VCAs. “First, it’s very small, and second, it’s very light. Portable devices that are attached to the patient’s body need to be as small and light as possible.” Featuring a diameter of 0.5 in., a length at midstroke of 0.5 in., force of 2.5 oz, and an actuator constant of 1.904 N per square-root watt, the compact component is designed to meet the tight packaging constraints of increasingly miniaturized medical devices.

Eight Breakthroughs in Medical Electronics
As design engineers continue to push the the boundaries of miniaturization and develop products that improve patient care, it is imperative that the electronic components at the core of many life-critical medical devices are able to keep pace with market needs. In this Web gallery, MPMN celebrates some of the superlative technology breakthroughs in the field of medical electronics that hit the market this year that show promise for driving the development of innovative, next-generation medical devices.
