Description: Facing the negative emotions of sadness and anxiety, our project aims to combine Artificial Intelligence with synthetic biotechnology to construct an emotion recognition and regulation device. In the recognition part, we use Convolutional Neural Network for facial emotion recognition,smart bracelet to record heart rate,and finally multimodal emotion judgment through software. In the regulation part, we focus on the sadness emotion, identify the judgment and start the blue light signal, thus stimulating E. coli EL222 photosensitive protein, initiating KdcA and Adh1 to catalyze the synthesis of PPA into phenylethyl alcohol, and releasing it through the aromatherapy system to achieve the emotional calming. Based on the overall closed loop, we further explored more extensions of light sources and emotion regulation, such as anxiety recognition into red light initiation and release of linalool regulation. Also extended such as music, light multi-sensory functions, in order to better assist the odor emotion regulation.
