a comparison of the time-averaged input power between a single SMA ribbon and two SMA ribbons at zero temperature span. b comparison of theoretical work recovery efficiency and measured work recovery efficiency. c coefficient of performance comparison between the baseline (without work recovery), system COP with work recovery, and materials COP, at zero temperature span, i.e. heat sink and heat source at ~ 294 K. The cooling power corresponding to the TiNiCu was 4.2 W at 0.12 Hz. The cooling power corresponding to the NiTi was 2.8 W at 0.12 Hz.
