Continuous monitoring of body‐surface vibrations via ambulatory sensing provides critical data for individual healthcare and human health mapping. However, the lack of deep structural integration along the entire skin‐to‐sensor acoustic pathway has rendered wearable mechano‐acoustic sensors incapable of balancing wearability and signal fidelity at the system level. Here, we report a flexible, skin‐interfaced triboelectric patch that addresses impedance mismatch through an internal corrugated sensing structure integrated with a membrane‐based resonant acoustic coupling interface. This architecture substantially augments mechanical‐to‐electrical transduction, encompassing the dominant energy spectra (0–1000 Hz) of physiological motions with a sensitivity of 2062.66 mV·Pa ^{− 1} ·cm ^{− 2} at 168 Hz with a low detection threshold of 45 dB. Then, a bispectrogram classifier based on the Cardiechema database is constructed, tuned, and evaluated via 5 × 3 cross‐validation, achieving a mean accuracy of 96.71% and a macro F1‐score of 96.72%. By synergizing high‐fidelity sensing with machine learning, this robust multimodal framework establishes a general approach for real‐time diagnostics and personalized healthcare, offering profound insights into complex physiological signatures from cardiac pathologies to intricate sleep architectures.

With the promotion of sustainability in the buildings and construction sector, the carbon saving strategies for the end-of-life (EoL) phase have been receiving increasing attention. In this research, life cycle assessment (LCA) theory was employed to study and compare the carbon savings benefits of three different management strategies (i.e., recycling, remanufacturing, and reuse) on the EoL phase of various buildings (including residential, office, commercial, and school buildings). Moreover, the carbon savings potential (CSP) was calculated and analyzed, which is defined as the percentage of the actual carbon savings to the sum of the total embodied carbon of the building. Results show that compared with traditional demolition and landfill treatment, the implementation of integrated management strategies for residential, office, commercial, and school buildings can reduce carbon emissions by 193.5–526.4 kgCO₂-e/m². Among the building materials, steel bar, structural steel, and concrete account for the major proportion of the total carbon savings of buildings (81.5–93.2%). The sequence of the CSPs for the four types of buildings, in descending order, is school, residential, commercial, and office buildings. A building with a life span of 50 years has the greatest CSP. The results of the study can be used to reduce environmental impacts, and have broad positive implications in terms of sustainable construction.
