Solar bioelectrical impedance spectrometer and bioelectrical impedance monitoring system having same

摘要

A solar bioelectrical impedance spectrometer includes a microprocessor module 201, a radio module 203 connected with the microprocessor module, a spectrometer module 205 connected with the microprocessor module, a battery management module 207, a battery module connected with the battery management module, a solar power supply management module 401 separately connected with the battery management module and the microprocessor module and a wearable solar cell module connected with the solar power 10 supply management module. The battery management module is configured for receiving current output from the solar power supply management module under a preset condition and charging the battery module by the current. The spectrometer module may include an impedance network analyzer, a differential amplifier connected with the impedance network analyzer, and a wide-band current source connected with the impedance network analyser. The solar supply management module may operate to enhance the power supply signal when light is relatively weak, directly supply power when the light is slightly stronger and charge the battery management module 207 when the light is relatively strong, such as under outdoor sunlight.
