It is known that liquid crystal materials exhibit phase transitions at specific temperatures. For electro-optical studies on liquid crystals, accurate temperature control is essential for maintaining their phases or inducing phase transitions. Moreover, many biological macromolecules present liquid-crystal-like behaviors. For optical microanalysis on biological thin films, accurate temperature control is also vital to keep cells or bio-molecules in active conditions. Since liquid crystal based thin-film display and biotechnology are two key industries that Taiwan has put emphases on, our proposed heater may provide a well-defined working station for research and development in academic and industrial applications. Combined with the principal investigators’ expertises, such as nonlinear optical microscopy on biological fibrous proteins and electromagnetic microanalysis on ferroelectric liquid crystals, the heater will provide a new research dimension on temperature-related studies.溫度迴授控制白金加熱器/熱感測器薄膜光電量測Temperature feedback controlplatinum heater/temperature sensorthin-filmelectro-optical characterization
