Voltage clamp. The voltage clamp is an experimental method used by electrophysiologists to measure the ion currents through the membranes of excitable cells, such as neurons, while holding the membrane voltage at a set level.
Based on the linear variable differential transformer (LVDT) principle, the performance of these sensors depends on inductance effects that do not involve flexing wires or sliding electrical contacts. All coils are magnetically shielded, and are cased in hardened stainless-steel housings.
