Biomedical sensors are devices that detect and measure biological signals from the human body. They can monitor various health parameters, such as heart rate, blood pressure, and glucose levels. These sensors play a crucial role in medical diagnostics, patient monitoring, and health management. These sensors often use advanced technologies, including microelectronics and biotechnology, to convert biological signals into readable data. They can be found in wearable devices, such as fitness trackers and smartwatches, as well as in clinical settings, helping healthcare professionals make informed decisions about patient care.
