Thermoacoustic (TA) loudspeakers was developed as a novel film speaker that utilizes temperature oscillation to vibrate the surrounding air. Conventional TA loudspeakers have been confronted problems when they got damage on their conductive networks, causing their malfunction. Therefore, introducing self-healing polymers in TA loudspeakers could be an effective way of restoring the damage of conductive networks. In this study, we present self-healable TA loudspeakers based on silver nanowire-poly(urethane- hindered urea) conductive electrodes. Our self-healable electrodes exhibit self-healing for repairing the damages that are caused due to the dynamic reconstruction. The fabricated self-healable TA loudspeakers generate a sound pressure level of 61 dB at 10 kHz. Developed TA speakers can recover the original sound after healing the electrodes. The proposed technique in this study provides powerful platform for the fabrication of TA loudspeakers with excellent self-healing property.
