Skin-Inspired Self-Aligned Silicon Nanowire Thermoreceptors for Rapid and Continuous Temperature Monitoring

without using any high-precision lithography. The sensors exhibited an excellent temperature coefficient of resistance of -1.8%/°C, enabling the precise spatial identification of heat sources. They achieved real-time monitoring of temperature changes during breathing and blowing activities, with a rapid response time of ∼0.2 s and recovery time of ∼1 s. This study provides a robust foundation for the integration of advanced miniaturized temperature sensors for biological monitoring applications.
