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. These electronics exhibit excellent wear resistance, high flexibility (>300% strain), biocompatibility, facilitating long-term interfacing cardiomyocytes collection (∼30 dB) cell field potential signals as well epicardial (∼42 from living rat models. This rapid straightforward approach improves precision integration metal-based flexible electronics, holding promise monitoring treatment, such mapping, electrical stimulation, other therapeutic interventions levels.
