transÂ·duÂ·cer. A device that converts energy from one form to another. transducer (tranzdooÂ´sur), n a device that is activated by power from one system and then supplies a different form of power to a second system; used to convert electric energy into mechanical energy in ultrasonic and sonic scalers.
Signal transduction will involve a receptor for the first messenger and may involve both transducers and effectors. In the field of receptors, a transducer may be defined as a molecule that translates one form of energy (e.g., the neurotransmitter) into another form, the second messenger. Effector is a molecule that mediates a specific effect (e.g., an ion channel).
