However, the realization of multifunctional sensing system on robots or prosthetics remains a huge challenge. Here we report a multifunctional tactile sensor fabricated from ionic thermoelectric gelatin that achieves simultaneous pressure and temperature detection. The thermoelectric effect of this ionic thermoelectric gelatin is mainly achieved through the synergy of the thermodiffusion effects and the thermogalvanic effect of ions. In addition, by applying pressure, the thermoelectric effect of this ionic thermoelectric gelatin can be changed (the thermopower of the ionic thermoelectric gelatin increases from 1.21 mV/K to 1.67 mV/K, representing a 38 % increase), so as to enable the sensor to sense external forces. By comparing the thermoelectric effect driven by temperature difference and the thermoelectric effect driven by pressure-temperature difference, there is a difference in the voltage response time. This allows for the decoupling of signals at the backend with only a simple algorithm. Using this sensor, we achieved a 95.31 % accuracy rate in identifying different materials. The multifunctional tactile sensor can promote the development of robots and better assist the disabled in restoring their sensory abilities.</div></div>","PeriodicalId":394,"journal":{"name":"Nano Energy","volume":"142 ","pages":"Article 111156"},"PeriodicalIF":16.8,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144104010","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The introduction of Cs greatly improved the NH<sub>3</sub> decomposition efficiencies, resulting in a decrease of 70 °C in reaction temperature for complete NH<sub>3</sub> decomposition over the Ru-MCM-41 catalyst. A series of characterizations indicate that there are interactions between Cs and Ru species that affect the physical and electronic properties of the Ru-MCM-41 catalysts.

By designing a hierarchical nanofiber sheath around a natural fiber yarn core, we endow traditional yarns with photonic interactivity. This yarn is compatible with existing textile manufacturing systems. The resulting fabric demonstrates high infrared emissivity (95 %) in the atmospheric window and high reflectivity (94 %) in the solar spectrum. This leads to an extraordinary increase in cooling power by 226 W/m² and a reduction in skin temperature by 7.0 °C compared to commercial fabrics under intense solar exposure. Moreover, the metayarn fabric exhibits exceptional wearability, including flexible color designability, excellent photonic structure stability, and satisfactory comfort.

This capability is attributed to the multi-resonance characteristics of the basilar membrane in the inner ear, which enables frequency selectivity by responding to different frequencies at different positions. Sensorineural hearing loss is a condition in which sound stimuli fail to be converted into neural signals due to inner ear damage. Although cochlear implants (CIs) can address this condition, issues related to the external components and battery dependency of CIs are still challenging. Artificial basilar membranes that mimic the human auditory system achieve frequency selectivity using a trapezoidal membrane, similar to the actual basilar membrane. However, this approach results in sensitivity loss due to different active areas for different frequencies and challenges in miniaturization. In this study, frequency selectivity was achieved in the range from 570 Hz to 8010 Hz while maintaining the constant active area within the frequency bandwidth by adjusting the mass and the spring constant. To enable self-powered operation, fluorinated ethylene propylene was used as the electret material, and the surface potential was enhanced through microstructural control via sintering.
