a Schematic of a textile-based strain-sensing choker. Two channels are aligned with the carotid artery and center of throat, respectively. Each channel consists of a two-terminal crack-based resistive strain sensor surrounded by a polyurethane acrylate (PUA) stress isolation layer. The top right SEM image shows the spontaneous ordered crack structure of the graphene coating. b Relationship between the response to uniaxial stretching (from 0.1% to 5%) and frequency. c Exploded view of the internal components of the PCB. d Diagram of the system communication. e Power consumption of each component during system communication. f Schematic of the high-resolution tokenization strategy.
