A Taiwanese doctor/scientist has developed a machine that can check your state of health in just 2 minutes The “Yin-Yang Instrument” reveals the secrets of the human body 台灣醫生科學家2分鐘檢測出健康研發陰陽儀 洞悉身體秘密


After 10 years of development, Professor Terry Kuo, Director of R&D at National Yang-Ming University, has developed a “Yin-Yang Instrument” that integrates the principles of Chinese and Western medicine and makes use of autonomic nervous system (ANS) biorhythm analysis. Simply pressing your hands down on this device reveals the secrets of the human body.


Professor Kuo, who is a qualified doctor, explains that Eastern medicine has traditionally divided people into people with yin constitutions and people with yang constitutions. People with a yin constitution tend to be more afraid of the cold and need more sleep; people with a yang constitution dislike hot weather and have a tendency to get over-excited. Western medicine divides the autonomic nervous system (ANS) into sympathetic nerves and parasympathetic nerves. Professor Kuo has integrated Western medicine’s ANS with the Chinese medicine concept of yin and yang, using the functioning of the parasympathetic nerves to represent yin and the functioning of the sympathetic nerves to represent yang; these indicators can be displayed using biorhythm analysis.


The famous Framingham study in the U.S. showed that, if the ANS falls by one standard deviation, the individual’s risk of death will be nearly twice that of a normal person. Using software programs and equipment that he designed himself, Professor Kuo has developed a biorhythm analysis device. If the graphical display shows a needle-point pattern, this indicates that the person’s yang is nearly exhausted. This ability to forecast possible death led Professor Kuo’s first-generation “Yin-Yang Instrument” to be described as a “fortune-telling machine.”


Professor Kuo undertook every stage in the creation of his biorhythm analysis device – including both the hardware and the software – himself, doing all of the circuit design and programming. He has succeeded in scaling down a large, bulky medical instrument to a personal device that is smaller than an i-Phone, and in converting complex software into an easy-to-understand graphical interface that uses the “Tai-ji” Yin-Yang symbol, making it simple and convenient for users to check their health status. All the user needs to do is to place both hands lightly on top of the device for two minutes; the instrument will then analyze the user’s ANS function. Having completed development of the third-generation of this device, Professor Kuo has formally named it the “Yin-Yang Instrument.”


Professor Kuo has created a pilot-production run of 100 third-generation Yin-Yang Instruments, which he has donated to National Yang-Ming University for use in basic research and in clinical experiments. Other universities and colleges, including Taipei Physical Education College and Tamkang University, have also started using these instruments for research purposes. For example, one university’s landscape design department has been using the devices to measure people’s emotional state before and after landscape creation, so as to be able to quantify the pleasure that people feel in a scientific manner.
