Review Questions
How does biointerfacing facilitate communication between biological systems and electronic devices?
Biointerfacing facilitates communication by enabling the conversion of biological signals into electronic formats that can be processed and analyzed. This interaction is crucial for biosensors, which rely on biointerfacing to detect specific biomolecules. Through carefully designed interfaces and materials, biological responses are captured and translated into measurable electrical signals, allowing for effective monitoring of physiological changes or the presence of pathogens.
