An electronic device that increases current, voltage, or power to intensify the electrical signal sent to or received from a transducer (e.g., electroacoustic, electro-optical, electromechanical), sometimes providing impedance matching. It will provide an electrical interface between a physiological transducer and a patient monitor or patient monitoring system that is used to monitor pressures such as, noninvasive and invasive blood pressure, oesophageal pressures, urinary tract pressures, intrauterine pressures and intraocular pressures.
