Electrical bio-impedance is a well-proven, powerful technique for analyzing a wide range of ionic and charge transfer processes in bio-materials. Until now, the use of impedance in bio-material applications has been limited by a number of factors, such as the ability to measure accurately the very low currents involved, and the need for safe working when performing experiments on living tissue. The 1294A Impedance Interface has been designed specifically to overcome these difficulties, and to meet the present and future needs of bio-material researchers everywhere.
