3-D graphene aerogel sphere-based flexible sensors for healthcare applications

This work reports comprehensive characterization of temperature sensing and force sensing capability of 3-D graphene aerogel spheres (GASs), which is a unique and super light graphene nanomaterial. 3-D Numerical simulations were applied to predict the electrical resistance changes of this hierarchical micro/nano material during deformation upon external forces. Moreover, we built GASs-based flexible sensors for three different healthcare applications such as tissue elasticity sensing, finger posture sensing and kinetic physiological signal sensing.
