Noninvasive Biopotential Sensors for Future Wearable Electronics

Noninvasive biopotential sensors have garnered considerable interest for their potential use in wearable electronics because of their capability to capture diverse physiological signals without piercing the skin. This approach presents multiple benefits over conventional invasive methods, including enhanced comfort and diminished risk of infection. The development of noninvasive biopotential sensors is a rapidly evolving field with numerous applications across healthcare, fitness monitoring, and human-machine interfaces. In the consumer electronics sector, there exists a significant demand for the reusability of biopotential sensors, rendering many technologies designed for the healthcare industry unsuitable for consumer electronic applications like wearable wristbands. This talk offers an overview of the current state of noninvasive biopotential sensors for future wearable electronics, encompassing various measurable biopotentials, such as electroencephalography (EEG), electromyography (EMG), and electrocardiography (ECG). It will also emphasize the challenges related to the materials used in noninvasive biopotential sensors, particularly in electrodes. Finally, the talk will spotlight the encouraging future prospects for noninvasive biopotential sensors, including their integration into wearable devices and the potential influence on human-computer interactions.
