类皮肤的温度和压力传感功能是下一代人工智能产品的基本功能。先前对电子皮肤和智能元件的研究主要集中在柔性压力传感器上，而使用单个设备同时灵敏地检测温度和压力仍然是一个挑战。在这里，我们报告开发基于微结构框架支持的有机热电（MFSOTE）材料的柔性双参数温度压力传感器。将温度和压力刺激有效转换为两个独立的电信号，可以实现温度和压力的瞬时传感，精确的温度分辨率<0.1 K，高压传感灵敏度高达28.9 kPa−1。更重要的是，这些双参数传感器可以自供电，具有出色的传感性能。基于MFSOTE的器件优异的传感性能，加上其低成本和大面积制造的独特优势，使得MFSOTE材料在电子皮肤和健康监测元件方面具有广阔的应用前景。 电子皮肤的构建需要同时检测温度和压力。这里是张等人。在单个自供电器件中利用独立的热电和压阻效应，其温度分辨率<0.1 K，压力灵敏度为28.9 kPa−1。
Skin-like temperature- and pressure-sensing capabilities are essential features for the next generation of artificial intelligent products. Previous studies of e-skin and smart elements have focused on flexible pressure sensors, whereas the simultaneous and sensitive detection of temperature and pressure with a single device remains a challenge. Here we report developing flexible dual-parameter temperature–pressure sensors based on microstructure-frame-supported organic thermoelectric (MFSOTE) materials. The effective transduction of temperature and pressure stimuli into two independent electrical signals permits the instantaneous sensing of temperature and pressure with an accurate temperature resolution of <0.1 K and a high-pressure-sensing sensitivity of up to 28.9 kPa−1. More importantly, these dual-parameter sensors can be self-powered with outstanding sensing performance. The excellent sensing properties of MFSOTE-based devices, together with their unique advantages of low cost and large-area fabrication, make MFSOTE materials possess promising applications in e-skin and health-monitoring elements. The construction of electronic skin requires simultaneous temperature and pressure detection. Here Zhang et al. utilize independent thermoelectric and piezoresistive effect in a single self-powered device, which shows a temperature resolution of <0.1 K and a pressure sensitivity of 28.9 kPa−1.
