Today, building materials emit many hazardous gases in the event of a fire, causing great harm to human health and the environment. Therefore, it is of great significance to develop bio-based flame retardant materials and to realize preventive measures to reduce fires or their damage. In this work, we fabricated a novel multifunctional fire early-warning polylactic acid-based fabric (MFR-PBF) by coating MXene nanosheet, phytic acid @ furfurylamine (PA@FA) and ammonium polyphosphate (APP) via an eco-friendly layer-by-layer assembly method. MFR-PBF showed outstanding flame retardancy including a limiting oxygen index value of 35 % and better char formation capacity. More importantly, MFR-PBF exhibited sensitive fire early-warning capability (∼1 s) and excellent cyclic alarm stability (>15 cycles) due to the excellent semiconductor responsiveness (light and heat) and the significant catalytic char formation effect. Moreover, MFR-PBF is comfortable, flexible and strong enough to sew onto firefighter uniform to detect a variety of human motions, which can be monitored in the internet by using a LoRa emitter and a gateway. In addition, the controllable heating performance rendered MFR-PBF as a potential portable heater. This work provides new insights into the preparation and application of intelligent fire early-warning fabrics in the smart fire protection and Internet of Things.

Wearable thermoelectric (TE)-based temperature sensors capable of detecting and transmitting temperature data from the human body and environment show promise in intelligent medical systems, human-machine interfaces, and electronic skins. However, it has remained a challenge to fabricate the flexible temperature sensors with superior sensing performance, primarily due to the low Seebeck coefficient of the TE materials. Here, we report an inorganic amorphous TE material, GeAsTe, with a high Seebeck coefficient of 1050 μV/K, which is around 3 times higher than the organic TE materials and 2 times higher than the inorganic crystal TE materials.

Earthquakes, as significant natural disasters, still cannot be accurately predicted today. Although current earthquake early warning systems can provide alerts several seconds in advance, acute stress responses (ASR) in emergency situations can waste these precious escape seconds. To investigate the correlation between personality and ASR, this study collected the temperament and character of all participants using the Chen Huichang-60 Temperament Scale and the DISC Personality Inventory.

Giving Timely warnings for fire is very crucial for fire prevention and the protection of people's lives and property. However, most current fire warning sensors give warnings above 200 °C, which are not conducive to efficient and accurate warnings. Therefore, it is important to develop high-temperature sensors that can give timely, portable warnings at low temperatures (100 to 200 °C).
