Abstract
Abstract Electronic components are constructed from a solid spherical core of electrically nonconducting material such as a stabilized cross-linked copolymer plastic. The spherical core is coated with a plurality of concentric electrically functional layers to provide a variety of electronic components such as resistors and capacitors having pressure sensitive electrical characteristics. More complex electronic components such as transistors, thermistors, rectifiers and thermocouples may be provided depending upon the configuration and composition of concentric layers on the spherical core. A plurality of spheres may be combined in a pressure chamber to provide a variety of transducers and detectors such as a pressure transducer, photosensitive detector, infrared detector or memory cell bank.
