Biomedical transducers participation in advanced diagnostic, therapeutic, and monitoring systems is continuously enhanced by the contribution of the advancements in electronic devices, equipment and automation, material sciences and signal and image processing, to register temperature, pressure, concentration of chemical molecules (gases, electrolytes, metabolites, and drugs), position, level, torque, velocity and acceleration, flow (blood, air), electrical activities of body systems (EMG, EEG, and ECG), among other variables. New and more efficient transducer technologies, which include the use of nanomaterials, fiber-optic, wireless and MEMS technologies, can contribute to greater safety, accuracy, and reliability of the use of medical transducers. In addition, new technologies tend to be low power and low cost, compared to conventional ones.
