- 摘要：
- Flexible pressure sensors capable of accurately detecting bidirectional wind pressure under extreme-temperature conditions are highly desirable for aerodynamic monitoring, but two major challenges remain. First, flexible sensors often suffer from insufficient reliability under the extreme temperatures encountered in aviation environments. Second, conventional flexible pressure sensors are typically designed for contact-based compressive load sensing, which limits their ability to simultaneously detect positive and negative wind pressures. Here, we report a highly linear flexible pressure sensor for bidirectional wind pressure measurement over a wide temperature range. Molecular spacing regulation of the sealing and dielectric materials enables reliable sensor operation from −70 to +140 °C. The rationally designed hermetic sealing structure and dielectric unit further enable highly linear capacitive responses to both positive and negative pressures over a broad pressure range from −100 to +100 kPa. Building on these advances, the flexible pressure sensor can be integrated onto the curved surfaces of aircraft models to measure wind pressure for lift calculation. This work provides an effective strategy for wide-temperature-range bidirectional wind pressure sensing, showing promising potential for aerodynamic evaluation and aviation monitoring.
