In this paper, we calculated chronaxy value in order to determine the optimal conditions and stimulus pulse of information transmission. We also developed an electrical equivalent circuit of the hand including the contact part, which consists of two resistors (a contact resistor and finger resistor) and a capacitor. The minimum recoulition voltage was measured by using electrical stimulus. We found that the ranges of the above two resistances and the capacitance are 30-130k$\Omega$, 20-60k$\Omega$ and 10-30nF respectively. We found that the minimum recoulition voltage was the lowest at 100-300Hz and 10% of the duty ratio.
