Abstract
A report is given on the development of a telemetric system for continuous recording of intracranial pressure, using an external energy source. The pressure transducer, called Teleceptor, is placed in the subdural space through a burr hole. The resonance frequencies of the transmitter and receiver circuits in the implanted transducer are influenced by a pressure-sensitive membrane in such a way that pressure variations result in resonance point displacement and energy transfer reduction. The necessary tuning of the transmitter frequency to maximum energy transfer is in direct proportion to the magnitude of pressure modification.
