Efficient Self-Cooling Polymer for Refrigeration

The research paper titled "Self-oscillating polymeric refrigerator with high energy efficiency" introduces an innovative electrocaloric (EC) thin-film device. This device leverages the synergy between electrocaloric and electrostrictive effects in polymeric ferroelectrics. Unlike traditional EC refrigerators that rely on external drivers, this new device operates autonomously, achieving a high coefficient of performance (COP) and cooling power density.
