- Abstract:
- Biopotential sensors are used in a wide range of biomedical applications. For example, measuring electric potentials on the surface of living tissues in electroencephalography (EEG), electromyography (EMG), and electrocardiography (ECG) systems in which the brain, muscle, and heart activities respectively are measured over time. Moreover, these electrodes are used in measuring the pH of different materials and also in receiving and recording the electric field changes of the environment. The major purpose of biopotential electrodes is to act as a transducer between the ionic transport of the tissue and the electron flow in the electrode. Such a transduction takes place due to an oxidation or reduction reaction occurring at the interface of the electrode and the electrolyte.
The noise reduction and artifact elimination are known as major issues in all of the biomedical applications in order to increase the accuracy, repeatability and reliability of measurements. These artifacts are arised due to the structure, type and material of the electrodes and also the noise level of the read out system. The purpose of this research is to design and fabricate an ultra low noise Ag/AgCl biopotential sensor in order to achive a low noise level below 10 nV/√Hz - Keywords:
