It is an object of the invention to provide a biological sensor capable of detecting a biological information with a high sensitivity. It is an object of the invention to provide a support system for carrying out a support in such a manner that a work can be efficiently performed based on the biological information obtained by the biological sensor. There are provided acceleration detecting means (300) constituted to detect an acceleration including a vibration of a body surface of a person to be measured, processing means for extracting at least two of an information about a heartbeat, an information about a body motion and an information about a breath from an information output from the acceleration detecting means (300), and deciding means (500) for deciding a condition of the measured person to be a living body from an output of the processing means.
A biological sensor comprising:
A biological condition deciding device for deciding a biological condition of a person to be measured based on an information output from a piezoelectric sensor having a flexibility, comprising:
A biological information detecting device comprising first vibration detecting means provided directly on a living body or provided on an object coming in contact with the living body and serving to detect a vibration of the living body, second vibration detecting means opposed to the first vibration detecting means and provided through vibration attenuating means having a preset vibration attenuating characteristic, first calculating means for calculating power spectra of respective output signals of the first vibration detecting means and the second vibration detecting means, second calculating means for calculating, every frequency, a difference between both of the power spectra calculated by the first calculating means, and third calculating means for obtaining, as an information about a heartbeat, a frequency at which the difference between the power spectra is maximized in a fundamental frequency region of the heartbeat which is preset based on a result of the calculation of the second calculating means.
A biological information detecting device, wherein a plurality of vibration detecting means provided directly on a living body or provided on an object coming in contact with the living body and serving to detect a vibration of the living body is disposed through vibration attenuating means having a certain vibration attenuating characteristic, and frequency components of respective outputs are obtained and a frequency at which a difference is maximized in a fundamental frequency region of a heartbeat is acquired as an information about the heartbeat.
A biological information detecting device comprising first vibration detecting means for detecting a vibration of a living body and second vibration detecting means opposed to the first vibration detecting means and disposed through vibration attenuating means having a vibration attenuating characteristic, a frequency component of an output signal of each of the first vibration detecting means and the second vibration detecting means being obtained and a frequency at which a difference is maximized in a fundamental frequency region of a heartbeat being acquired as an information about the heartbeat.
