This paper presents a strategy for preparing multifunctional sensors with dual-modal responsive capabilities, achieving ultrahigh pressure sensitivity and ammonia sensitivity, along with excellent durability and rapid response time. The sensor can perceive human activities and surrounding status, paving a valid path for constructing high-performance electronic devices.
Achieving the desired sensors possessing multimodal sensory abilities and robust environmental degradability is critical for the practical applications of flexible wearable electronic devices. Herein, a facile and efficient strategy for preparing multifunctional sensors with a dual conductive network by sequential decoration of reduced graphene oxide and polyaniline onto the air-laid paper fibers is proposed. Such a design provides the fabricated sensor with dual-modal responsive capabilities, reaching an ultrahigh pressure sensitivity of 143.41 kPa(-1) and an ammonia sensitivity of 0.036 ppm(-1). The as-prepared sensor also exhibits a remarkable durability (5000 cycles), rapid pressure response time (70 ms), gas response time (30 s) and wide pressure-working range (0.005-40 kPa). The degradation experiment shows that the sensor possesses an excellent degradability, implying that it is free of environmental pollution. It can be utilized to perceive the human activities and surrounding status, thereby paving a valid path for constructing high-performance electronic devices.
