a schematic view of spray-on-skin sensor fabrication. b optical image of spray-on-skin sensor. c SEM view of spray-on-skin sensor on the skin cast, showing the conformability of the sensor. d Eight gestures recognized in this research. Each gesture was mapped to an action of a plane model in VR. e gestures and their signals. f unsupervised clustering result of 8 different gestures. g confusion matrix using a convolutional neural network for recognition. h a piece of gesture signal and its control output.
