Galvanic skin response readout
A second wire is connected from the device to a probe, which the operator touches to “acupuncture points” on the patient’s other hand or a foot. The device emits a tiny direct electric current that flows through a wire from the device to a brass cylinder covered by moist gauze, which the patient holds in one hand.

Actually, most devices are little more than fancy galvanometers that measure electrical resistance of the patient’s skin when touched by a probe. Proponents claim that these devices measure disturbances in the body’s flow of “electro-magnetic energy” along “acupuncture meridians.” Some are claimed to measure “vibrations,” “resonance,” or “stresses” associated with body tissues and/or organs. Subsequent variants include the AcuGraph, Accupath 1000, Asyra, Avatar, BICOM, Bio-Tron, Biomeridian, BioScan, BioTracker, Computron, CSA 2001, DBE204, Diacom, DiagnoMètre, Eclosion, e-Lybra 8, ELAST, Interactive Query System (IQS), Interro, I-Tronic, Kindling, LISTEN System, Matrix Physique System, Meridian Energy Analysis Device (MEAD), MORA, MSAS, Oberon, Omega Acubase, Omega Vision, Orion System, Phazx, Prognos, Prophyle, Punctos III, Quest4, Sensitiv Imago, SpectraVision, Syncrometer, Vantage, Vitel 618, and ZYTO. A few years later, one of his students (another German physician named Helmut Schimmel) simplified the diagnostic system from approximately 850 points to 60 points, made small modifications to the equipment, and went on to help create the first model of the Vegatest. His first transistorized model was the Dermatron. In 1958, he combined Chinese acupuncture theory with galvanic skin differentials to produce his EAV system. The first EAV devices were developed by Reinhold Voll, a West German physician who had been engaged in acupuncture practice in the 1950s. EAV devices are marketed by several companies, most of which also sponsor seminars. The diagnostic procedure is most commonly referred to as Electroacupuncture according to Voll (EAV) or electrodermal screening (EDS), but some practitioners call it bioelectric functions diagnosis (BFD), bio resonance therapy (BRT), bio-energy regulatory technique (BER), biocybernetic medicine (BM), computerized electrodermal screening (CEDS), computerized electrodermal stress analysis (CDCSA), electrodermal testng (EDT), limbic stress assessment (LSA), meridian energy analysis (MEA), or point testing. One Mexican clinic even claimed that such a device could be used to cure cancer. Some claim they can tell whether a disease, such as cancer or AIDS, is not present. Some also claim that the devices can detect whether someone is allergic or sensitive to foods, deficient in vitamins, or has defective teeth. Many claim to determine the cause of any disease by detecting the “energy imbalance” causing the problem. In the near future, conductive yarns will be used for the interconnections instead of general Cu wires and we are going to measure the emotion change from physiological signals from human body during usual life.Thousands of practitioners use “electrodiagnostic” devices to help select their recommended treatment.
Galvanic skin response readout software#
Measured data from sensors were signally processed and transmitted using via Bluetooth 4.0 wireless network, so we could display successfully those data using software on the lab-top computer. And GSR data were measured at the skin with high sensitivity and normal atmosphere to compare. Finally, flexible temperature sensor of the fabricated smart band module was tested at the surfaces of ice pack, desk, and hot plate with temperature in the range of 4.5 ∼ 74.1̊C including skin temperature around 30 ∼ 33 ̊C. And then two modules were interconnected with Cu wires. Smart band module largely consisted of two parts, one was flexible sensors module and the other one was signal processing and communication module. In order to monitor health usually, the wearable type smart band module to measure the physiological signals from human body was designed, fabricated and characterized.
