Bioelectric sensors are devices that detect and measure biological signals, such as electrical activity from cells or tissues. They work by converting these signals into readable data, which can be used for various applications, including medical diagnostics and environmental monitoring. These sensors often utilize materials that can interact with biological systems, making them sensitive and effective. These sensors can be found in many forms, such as electrocardiograms (ECGs) that monitor heart activity or glucose meters for diabetes management. By providing real-time information, bioelectric sensors play a crucial role in advancing healthcare and improving patient outcomes.
