TL;DR: The ferroelectret nanogenerators' intrinsic properties that allow for the bidirectional conversion of energy between electrical and mechanical domains are reported, extending its potential use in wearable electronics beyond the power generation realm.

TL;DR: The added functionality establishes a link between optical and mechanical domains of high-performance photoactuators and enables the future development of mechanical logic gates and electronic devices that are triggered by optical radiation from different frequency bands.

TL;DR: In this article, a polypropylene ferroelectret (PPFE) is introduced as the active material in an efficient, flexible, and biocompatible FENG device.

TL;DR: This work reports a VO2-based actuator technology that incorporates single-wall carbon nanotubes (SWNTs) as an effective light absorber to reduce the amount of photothermal energy required for actuation and shows that the combination of VO2 and SWNT thin films is an effective approach to increase the photothermal efficiency ofVO2- based actuators.

TL;DR: This work uncovers two distinct regimes of the dynamical phase change: a nearly instantaneous crossover into an intermediate state and its decay led by lattice instabilities over 10 ps timescales.
