The actuator is implemented based on the conductive polymer layer which causes photothermal conversion through the light in the near infrared region. The photothermally induced heat from conducting polymer can be converted into other type of energy such as mechanical, electrical or chemical energy. Especially, photothermal energy conversion into mechanical energy gives a unique method for reversible change of multi-layered actuator from 2-dimensional to 3-dimensional structure by thermal expansion coefficient mismatch among the layers. Herein we present the effect of the layer composition on the photoactuation and demonstrate a light switchable photothermal sensor.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for 2018 presentations, with transcripts for prior recordings added daily.
