We demonstrate that trimethylamine borane can exhibit desirable piezoelectric and pyroelectric properties. The material was shown to be able operate as a flexible film for both thermal sensing, thermal energy conversion and mechanical sensing with high open circuit voltages (>10 V). A piezoelectric coefficient of d 33 ≈10–16 pC N −1 , and pyroelectric coefficient of p ≈25.8 μC m −2 K −1 were achieved after poling, with high pyroelectric figure of merits for sensing and harvesting, along with a relative permittivity ofϵ 33 σ ≈ 6.3.
