Published: March 30, 2025
Mechanical mismatches at the microscale between bioelectronics and cells severely hinder successful acquisition of high-quality stable electrophysiological signals. Room-temperature liquid metals (EGaIn), which possess a near-zero Young's modulus, present promising material for achieving conformal contact with biological tissues. However, fluidity limits elastic encapsulation patterned circuits cellular resolution. To address this challenge, we develop bilayer microfluidics-based method to elastically encapsulate high-resolution electrode array (20 μm) within several minutes (<3 min). The alignment-free overcomes limitations packaging polymers aligners, enabling cost-effective, scalable manufacturing devices.
