Description
Technical field
This utility model belongs to skin resistance signal detection apparatus field, specifically a kind of Skin resistance sensor.
Background technology
At present good acquisition method also be there is no to the change of the emotion of people, and relatively more urgent to the needs of emotion analysis clinically, and especially in psychological medicine, the emotion changes grasping patient is significantly.
By the detection to human body forefinger and middle interphalangeal skin resistance, there is very important meaning to the emotion changes of analyst.The saying of the second brain that the traditional Chinese medical science has hands to behave, the emotional activity of people can have influence on the secretion of perspiration on hand and the flowing velocity of blood.
Utility model content
For the technical problem existed in prior art, this utility model provides a kind of Skin resistance sensor, this Skin resistance sensor is by changing the skin resistance of forefinger and middle interphalangeal, and the real time reaction variation tendency of patient's emotion, has the advantages such as higher sensitivity.
To achieve these goals, the technical scheme that this utility model adopts is: a kind of Skin resistance sensor, includes:
First test electrode, the second test electrode, fix with forefinger and middle finger respectively;
External drive circuit, output drive signal also exports the first test electrode, the second test electrode to;
Computing and control circuit, the voltage signal the first test electrode, the second test electrode fed back to is changed through A/D convertor circuit and is calculated to be resistance value, and controls the driving frequency of the pumping signal that external drive circuit exports;
Usb communication circuit, the resistance value signal that computing and control circuit export is uploaded to terminal unit, and terminal unit sends instruction and sends different driving frequencies with control algorithm and control circuit.
Preferably, described terminal unit comprises mobile phone or computer.
Further, described first test electrode, the second test electrode are fixed on forefinger, middle finger respectively by a degree of tightness fixing band, described external drive circuit, computing and control circuit and usb communication circuit are all integrated in box body, and this box body is connected with the first test electrode, the second test electrode and USB interface respectively by wire harness.
Skin resistance sensor of the present utility model, compared with prior art, its beneficial effect shows:
1), this utility model by two electrode special bands on forefinger and middle finger, circuit extrinsic motivated voltage, detect two point between the variable signal of resistance, by the process such as AD conversion, mathematical operation, then export real-time resistance variations data by USB interface.
2), this utility model by changing the skin resistance of forefinger and middle interphalangeal, the real time reaction variation tendency of patient's emotion, has higher sensitivity.It is unstable or exciting that resistance decreasing reflects measured's emotion trend.Reflect measured's emotion trend when resistance becomes large stable, mood is gentle, and this Skin resistance sensor is the effective means doing psychological study and psychological intervention.
