James E. West AT&T Bell Laboratories, Murray Hill J He developed the foil-electret transducer for sound recording and voice communications, which is the heart of most new telephones manufactured today. These developments sprung from his U.S. patent #3,118,022 (1964) entitled "Electroacoustic transducer." West's pioneering research on charge storage and transport in polymers led to the development of the electret transducer. This transducer is simple yet rugged, which has made it ideal to serve as the heart of most new telephones. In addition to applications of transducers in areas related to telecommunications equipment, West developed inventions for other applications, including use of electret transducers for blood pressure measurements. He also has significant inventions in the area of directional microphones among his 33 patents. |
