The ZYTO Hand Cradle is the industry leading hardware device cleared by the Food and Drug Administration for the measurement of Galvanic Skin Response (GSR). ZYTO’s many software offerings use the GSR data gathered by the ZYTO Hand Cradle to assist its customers in serving their clients. The Hand Cradle interfaces with the body to provide quick, accurate readings of GSR.

 

ZYTO Hand Cradle technology is based on established scientific principles that date back to 1849, when physician and physiologist Emil du Bois-Reymond discovered that skin was electrically active. In 1879, Dubois-Reymond’s work was advanced further when French neurologist Charles Fere found that skin resistance could change based on emotional stimulation.

Now, over 150 years later, electrodermal activity (EDA), a term now used synonymously with GSR, has been the subject of hundreds of professional publications. Those who may be skeptical that a device can accurately measure GSR need only look at the scientific studies contained in many of these publications to find that the technology is anything but pseudoscience.

 

Using GSR data gathered by the ZYTO Hand Cradle, the ZYTO Balance software runs automated biosurveys, including unique library inventory features, to accomplish several objectives:
 

• Identifies specific nutritional supplements and essential oils
  for which you show a biological coherence.

• Evaluates more than 190 biomarkers and identifies key biomarker areas for you to consider.
