A biomedical recording system is a device that measures bio-potentials and graphically records or reproduces waveforms. These systems record the electrical activity of various body systems, such as cardiac muscles, neuronal cells, and skeletal muscles.  Biomedical recorders use electrodes to pick up bioelectric potentials and transducers to convert physiological signals into usable electrical outputs.  Some types of recorders used in biomedical instrumentation are:  Strip chart recorders, Galvanometric recorders, Potentiometric recorders, Ultraviolet recorders, Inkjet recorders,...
