The field of bioelectronic interfaces has witnessed remarkable progress, driven by the need for advanced solutions in neural and cardiac monitoring. These interfaces are critical for understanding and interacting with biological systems at a cellular level, paving the way for innovative diagnostic and therapeutic applications. Microfabrication techniques play a pivotal role in miniaturizing these devices, enhancing their sensitivity, and enabling seamless integration with biological tissues, thereby improving signal acquisition and reducing invasiveness [1].
The development of flexible and stretchable bioelectronic sensors is paramount for achieving minimally invasive neural recording. These novel materials and fabrication methods allow interfaces to conform to the complex geometries of biological surfaces, leading to superior tissue integration and enhanced signal fidelity compared to traditional rigid electrodes. Ensuring biocompatibility and long-term performance in dynamic physiological environments remains a key focus of this research area [2].
A significant advancement has been the creation of wireless, implantable microelectrode arrays specifically designed for chronic cardiac monitoring. These interfaces leverage microfabrication for miniaturization and employ energy-efficient wireless power transfer and data telemetry. Their potential for continuous, long-term assessment of cardiac electrophysiology without external connections is crucial for managing conditions like arrhythmias [3].
Conductive polymers are emerging as transformative materials for bioelectronic interfaces, particularly in neural stimulation and recording. These polymers enhance electrode conductivity and biocompatibility, resulting in improved signal-to-noise ratios and minimized tissue damage.
