• • The eutectogel achieves a resilience of 97.8% and a conductivity of 48.02 mS m−1, enabling reliable signal transduction and mechanical recovery in TENG-based pressure sensors, critical for long-term cyclic operation.
• • At −40 °C, the eutectogel retains 75.7% tensile and 69.4% compressive resilience, demonstrating anti-freezing performance essential for sensors deployed in polar or high-altitude environments.
• • After 24 h storage under −0.1 MPa vacuum, no significant change in resilience is observed, confirming vacuum tolerance for aerospace or low-pressure industrial applications.
• • The TENG pressure sensor shows a fast response time of 16 ms and stable output over 16,000 contact-separation cycles, ensuring durability and precision in high-frequency pressure monitoring.
