SENSOR AND SYSTEM FOR MEASURING OF PULSE WAVE

摘要

PURPOSE: A sensor and a system for measuring of a pulse wave are provided to stably measure a pulse wave of a body to be measured by measuring the change of magnetic field between first and second magnetism generators. CONSTITUTION: A case(11) supports a first magnetism generator(12) which generates magnetic field which is reference for measuring the change of magnetic filed through a bias supplied from the outside. A second magnetism generator(13) generates magnetic field while being vibrated according to the pulse wave of the human body. A hall sensor(14) senses the change of the magnetic field generated between the second magnetism generator and the first magnetism generator. At least one of the second magnetism generator and the hall sensor is comprised of a plurality of arrays.
