Electrical Properties of Platinum Tipped Micro‐electrodes in Ringer's Solution

This is the authors' abstract. We don't add key points for this paper.

Summary. Measurements of the impedance of Bhodium and Pt‐black tipped electrodes of < 10 Mu diameter have been made. The impedance changed with frequency according to recognized equations and the 1.1 Kcyc./sec. value varied from 0.23 to 1.29 M. Under stable conditions, and in conjunction with high impedance recording devices, it has been shown that the electrodes recorded potentials of very low frequency with negligible distortion.
