A skin impedance measuring device and method includes: an electrode system having at least two electrodes placed on the skin; an adjustable voltage output unit to generate forward and reverse voltages on the electrodes; a skin impedance measurement unit to measure electrical signals from the electrodes; a central processing unit and a computing memory for calculating forward and reverse skin impedances, determining whether the measurement results are abnormal, and correcting abnormal results by delivering additional DC or AC voltages of adjustable magnitudes and frequencies based on impedances; and a display unit.

Device and method for dynamic skin impedance measurement and correction

An automatic acupuncture device includes: a case; a motor or an electromagnet; a needle driver, configured to move linearly under the force of the motor or electromagnet to drive an acupuncture needle in a needle gadget into a human body, the needle gadget comprising a needle tube and an acupuncture needle inside the needle tube; a needle gadget chamber configured to house the needle gadget; and a locking-releasing structure that is configured to lock the needle gadget so that it will not fall out of the needle gadget chamber during acupuncture treatment, and also configured to release the needle gadget from the needle gadget chamber after acupuncture treatment. A needle gadget is provided for use with the acupuncture device, so that the acupuncture needle will not be exposed in air outside the needle tube before or after acupuncture. The acupuncture process is automatic, safe, without complicated manual operation.

A biosensor is described which can obtain physiological data from an individual. The biosensor may collect electrodermal activity, skin temperature, and other information. The biosensor may be attached to the body through the use of a garment which may be fastened in multiple locations on the human body. The biosensor includes compensation for electrodermal activity measurements based on the amount of pressure applied to the electrodes that are in contact with the skin. As pressure is increased the electrodermal activity values typically increase. By compensating for the influence that pressure changes have on electrodermal activity, more accurate analysis of physiology and therefore mental state analysis may be performed.
