Research Abstract

A system was proposed for measuring neural activity with high signal to noise ratio and non-invasive character, by using a skin hair as a biological probe. To see through an internal structure of a skin hair, I used a white hair of rabbit. To make the hair conductive, both ends of the hair is soaked in electrolyte solution, and tested with different combination of concentration and time for absorption. As a result conditions for using a skin hair an electric cable have been clarified.
