Abstract

Abstract: 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 of ϵ 33 σ ≈ 6.3. Abstract : Pyroelectrics are borane : Plasticity and mechanical flexibility in trimethylamine borane are harnessed to generate a piezoelectric and pyroelectric flexible film for sensing and energy harvesting applications.
