Development of a robust vibration unit for an e-textile haptic feedback system

In this paper a design research project for the creation of a surface mounted vibrotactile component for an e-textile system is performed. This is done as a constituent part of the Mo- tionVibe research project, this is a project to design a smart sensing haptic feedback system for running injury prevention in the lower extremity. A modified double diamond research model is employed to answer the question; How can a haptic feedback module for a smart sensing e-textile system be designed to perform and survive when used at high frequency with high exposure running conditions? Extensive background research is conducted cov- ering both a similar research project which was completed for the same MotionVibe system and several topics relevant to the field of e-textiles and wearables. These topics include; the usability of wearable devices, ingress protection, e-textile component mounting, e-textile configurations, running, biomechanics, and human morphology.
