Portable and wearable dual-mode sensors that can simultaneously detect multiple stimuli are essential for emerging artificial intelligence applications, and most efforts are devoted to exploring pressure-sensing devices. It is still challenging to integrate temperature and pressure-sensing functions into one sensor without the requirement for complex decoupling processes. Herein, we develop a self-powered and multifunctional dual-mode sensor by dip-coating melamine sponge with both poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) and carboxylated single-walled carbon nanotubes (CNTs). By integrating thermoelectric and conductive PEDOT:PSS/CNT components with the hydrophilic and resilient porous sponge, the resultant sensor is efficient in independently detecting temperature and pressure changes. The temperature and pressure stimuli can be independently converted to voltage and electrical resistance signals on the basis of the Seebeck and piezoresistive effects, respectively. The sensor exhibits a high Seebeck coefficient of 35.9 μV K–1 with a minimum temperature detection limit of 0.4 K and a pressure sensitivity of −3.35% kPa–1 with a minimum pressure detection limit of 4 Pa. Interestingly, the sensor can also be self-powered upon illumination. These multi-functionalities make the sensor a promising tool for applications in electronic skin, soft robots, solar energy conversion, and personal health monitoring.

具有热电聚（3,4-乙烯二氧噻吩）：聚（苯乙烯磺酸盐）和碳纳米管的自供电弹性多孔传感器，用于灵敏的温度和压力双模传感
可以同时检测多个刺激的便携式和可穿戴双模传感器对于新兴的人工智能应用至关重要，并且大部分努力都致力于探索压力传感设备。将温度和压力传感功能集成到一个传感器中而不需要复杂的去耦过程仍然具有挑战性。在此，我们通过在三聚氰胺海绵上浸涂聚（3,4-乙烯二氧噻吩）：聚（苯乙烯磺酸盐）（PEDOT：PSS）和羧化单壁碳纳米管（CNT），开发了一种自供电和多功能双模传感器。 . 通过将热电和导电 PEDOT:PSS/CNT 组件与亲水性和弹性多孔海绵集成在一起，所得传感器可有效地独立检测温度和压力变化。根据塞贝克效应和压阻效应，温度和压力刺激可以分别独立地转换为电压和电阻信号。该传感器具有 35.9 μV K 的高塞贝克系数–1，最低温度检测限为 0.4 K，压力灵敏度为 -3.35% kPa –1，最低压力检测限为 4 Pa。有趣的是，传感器也可以在照明时自供电。这些多功能性使传感器成为电子皮肤、软机器人、太阳能转换和个人健康监测应用的有前途的工具。
