Abstract
Developing sensors with multi-sensory detection capabilities will streamline integrated systems and simplify the integration process. Herein, dual-mode temperature and pressure sensors based on PEDOT: PSS/CNTs/CNF/MXene (PCCM) is established. In terms of temperature sensing, the aerogel structure and introduction of MXene provide ultra-low thermal conductivity, ensuring a stable temperature gradient. The addition of CNTs forms an excellent conductive network, significantly enhancing temperature sensing performance and achieving a maximum Seebeck coefficient of 28.2 µV K<sup>−1</sup>, the introduction of MXene ensures PCCM the output electrical signal has ultra-low noise and a high signal-to-noise ratio, allowing the detection of temperature differences as small as 0.05 K. Regarding pressure sensing, the sensitivity exhibited in the low-pressure range (0–4 kPa) is −11.44% kPa<sup>−1</sup>. Additionally, MXene significantly increases the sensor's electrical conductivity, reducing electron scattering and obstacles, shortening the response and recovery times (120 ms) for pressure measurements, and combining with CNTs/CNF increasing the hardness of the PCCM sensor, thereby expanding the pressure measurement range (0–20 kPa). It also highlights its promising potential for skin-like sensing and human–computer interaction applications by developing a multimodal intellectual panel. This work provides a simple and scalable fabrication method to design high-performance multifunctional sensors for various applications, such as e-skin and robotics.
