Development of 3D Reversible Smart Energy-Saving Devices for Adaptive Energy Management.

ABSTRACT: Conventional 2D thin-film-based energy-saving devices face limitations in controlling phase transition temperatures and in material selectivity. In contrast, 3D devices offer better temperature tunability and broader material options for surface coatings. However, existing designs still face challenges like limited deformation and asymmetric structures, hindering adaptation to varying sunlight incidence and azimuth angles. This study proposes symmetric 3D devices incorporating a shape memory alloy actuator, black paint for solar absorption, and a polydimethylsiloxane (PDMS)/Al₂O₃ composite as an RC film, exhibiting the following characteristics: i) reversible, continuously tunable 3D mechanical deformation between solar heating (SH) and radiative cooling (RC) modes vi
