What pivotal microphone technology did James West help develop at Bell Laboratories?
Answer
The electret microphone
The electret microphone utilizes a dielectric material with quasi-permanent electric charge or dipole polarization. This innovation allowed for the creation of microphones that were much smaller and more efficient than previous condenser microphone designs, which required bulky external power sources. By eliminating the need for external polarization voltage, West and his colleague Gerhard Sessler revolutionized audio recording by enabling the miniaturization of acoustic devices.
