To help future dentists and dental assistants deal with children during dental treatments, the Japanese company tmsuk has developed a humanoid robot that realistically simulates the behaviour of young children during these treatments, complete with fidgeting, flinching or closing the mouth. The dummy’s realistic movements are produced using proportional pressure regulators with piezo technology.

These valves offer high-precision flow control at up to 20 l/min. – with low hysteresis, high repeat accuracy and low energy consumption. The proportional characteristics of a piezo bender with direct actuation ensure stable and reliable regulation – and a stepless pressure rise.
