Biomedical Sensors

A biomedical sensor measures several aspects of our body, such as temperature, heart rate, and blood pressure. They are typically non-invasive, which means they do not breach the skin, and they are employed in a variety of medicinal applications.

Biomedical sensors are devices that measure biological or medical parameters like temperature, heart rate, blood pressure, or glucose levels. Some examples of commonly-used biomedical sensors include ECG (electrocardiogram) sensors, blood glucose sensors, and pulse oximetry sensors. Biomedical devices can be installed in hospitals, clinics, and homes for remote monitoring or therapy purposes.
In order to make such biomedical sensors more accurate, sensitive and specific, researchers are actively working to develop new materials and technologies. Furthermore, the aim is to also create them smaller in size and at lower cost for greater accessibility.
A biomedical sensor is a type of device that measures biological or medical parameters such as temperature, heart rate, blood pressure, and glucose levels in the blood. These sensors are used for numerous different purposes such as medical diagnosis, remote monitoring, and therapy. They come in many forms including wearables, implantable devices, and diagnostic equipment and are found everywhere from hospitals to patients' homes. Biomedical sensors often involve electrocardiogram (ECG) sensors, glucose sensors,and pulse oximetry sensing. Currently biomedical sensor development is an active field with advances being made to produce more precise small sensors that are also easy to use and cost effective.


1.What is a Biomedical sensor?

  • Biomedical sensors are tools that detect specific biological, chemical, or physical processes and then transmit or report this data. They are mainly used to monitor the safety of the food, medicines, and environmental conditions.

2.What is the use of Biomedical sensors?

  • The chemical and biomedical sensors are most frequently used for detecting and monitoring the physical or chemical properties of various substances. In medicine and biotechnology, Biomedical sensors are tools that detect specific biological, chemical, or physical processes and then transmit or report this data. Biomedical Sensors may also be components in systems that process clinical samples.

3.What are the types of Biomedical sensors?

  • Biomedical sensors are divided into 3 major types:
    • Physical Sensors: These biomedical sensors are designed to measure blood pressure, body temperature, body flix, viscosity of the blood and biological magnetic field.
    • Chemical Sensors: These biomedical sensors are utilized to detect the concentration and ingredients of body liquid such as PH value, Ca+ concentration, glucose concentration and similar types.
    • Biosensors: These are used to sense enzymes, antigen, antibody, hormone, DNA, RNA and microbe. Biosensor is a kind of chemical sensor, which is mainly used to detect biological signals.
