Artificial intelligence (AI) and machine learning (ML) lead a new era in remote health monitoring and preventive care, while making ZnO based strain sensor and nanogenerators a very attractive data collection tool. Here, we demonstrate flexible piezotronics strain sensor/nanogenerator, based on chemically modified graphene aerogels to monitor human hand/finger motions as well as gait asymmetries. The I-V characteristic of the sensor shows high sensitivity towards detection of human motion with a good gauge factor of as high as 95 has been demonstrated.
