The Introduction to Biomedical Instrumentation Systems. Some of the areas covered include: The sources of biomedical signals, Performance requirements of biomedical instrumentation systems, factors to consider when designing biomedical instruments, etc.
Reliable temperature measurement is dependent on several factors that, more or less, inexorably lead to measurement errors. In this article…
Bioinstrumentation involves the measurement of current or voltage signals from the different parts of the body. The measurement of various…
We have the following five types of biomedical instrumentation/measurement systems: Direct/Indirect Invasive/Non-invasive Contact/Remote Sense/Actuate Dynamic/Static Direct/Indirect In biomedical instrumentation we…
Medical isolation amplifiers provide an ultra-low conductive pathway between the input (patient) terminals and the output terminals and ground. This…
Biological signals are often very minute and typically contain unwanted interference or noise. Such interference has the detrimental effect of…
The principle of operation of liquid crystal sensors is based on the fact that liquid crystals change their state in…
Biopotential amplifiers are also termed to as Bioamplifiers. Bioelectric measurements are normally low-level voltages with high source impedances therefore signal…
In a Biomedical measurement system, the electrodes pick up the bioelectrical potential whereas the transducer converts the physiological signal to…
Signal amplification is essential part of any biomedical measurement. Bioelectric measurements are usually low-level i.e. microvolt level measurements, therefore amplification…
The information obtained from a medical sensor or transducer is usually in form of current intensity, voltage level, frequency or…
