SKIN MOISTURE TESTING SYSTEM AND METHOD

摘要

A skin moisture testing system comprises a Bluetooth MCU control unit, a Bluetooth antenna impedance matching unit, a RC integral and diode rectifier unit, a sinusoidal signal unit, a first contact, a second contact. A skin moisture testing method matches with a lower powered Bluetooth MCU to test a user's skin for a long time, and the tested skin moisture value can be visually displayed on the APP of the terminal device, the testing data can be made to form a graph.

1. A skin moisture testing system, comprising,
a Bluetooth MCU control unit, a Bluetooth antenna impedance matching unit including an IC matching circuit and a terminal matching circuit, a RC integral and diode rectifier unit, a sinusoidal signal unit, a first contact, a second contact, the first contact and the second contact in contact with skin of a user; the sinusoidal signal unit transmitting a square wave high frequency sinusoidal signal emitted by the Bluetooth MCU control unit to the first contact, the second contact receiving a first signal via the Bluetooth MCU control, the first signal filtered and shaped by the RC integral and diode rectifier unit to a second signal, the Bluetooth MCU control unit sampling the second signal to get a plurality of samples, the plurality of samples quantified to get a semaphore value; the Bluetooth antenna impedance matching unit translating the semaphore value into a skin impedance value, the skin impedance value is translated into a skin moisture content value corresponding to the skin impedance value, the Bluetooth antenna impedance matching unit matching with the Bluetooth MCU control unit, and partly matching with an on board antenna of the Bluetooth antenna.
