However, detecting temperature and pressure simultaneously with a single sensor without signal interference is challenging. Herein, a novel PCC aerogel sensor composed of PEDOT:PSS, CNTs, and CNF via directional freezing technology is developed. The PCC sensor can decouple temperature and pressure stimuli into individual voltage and resistance signals. It exhibits high-precision temperature sensing capabilities, boasting an exceptionally high Seebeck coefficient of 30.4 µV K-1 and the ability to detect temperature variations as low as 0.1 K. PCC sensors show excellent sensitivity and fast response times for detecting static and dynamic pressures, as well as high stability after 1000 cycles. Its maximum pressure sensitivity can reach 159.1% kPa⁻¹, and the lowest detection limit is 10 Pa. Additionally, its excellent thermoelectric properties also enable to generating thermopower from human skin for self-powered pressure sensing. A 3×3 PCC sensor array has been proposed to simulate the unique features of human skin in temperature and pressure recognition. This work provides a scalable manufacturing strategy for multi-functional tactile sensors. date: 2024-05-03 date_type: published publisher: Wiley official_url: https://doi.org/10.1002/admt.202400096 full_text_type: other language: eng verified: verified_manual elements_id: 2276074 doi: 10.1002/admt.202400096 lyricists_name: Lan, Yang lyricists_id: YLANX71 actors_name: Lan, Yang actors_id: YLANX71 actors_role: owner full_text_status: restricted publication: Advanced Materials Technologies article_number: 2400096 issn: 2365-709X citation: Wang, Zubin; Jiang, Saihua; Huang, Yubin; Song, Tao; Liufu, Chaokang; Huang, Yangchun; Zhou, Gang; ...
