The aim of the project is to develop a personalized smart insole system for older workers to reduce back pain. The SIFOOtWORK system will consist of an insole that, equipped with pressure sensors, can measure the lifting workloads of older workers. By integrating state-of-the-art low power technology, Narrowband IoT (NB-IoT) communication, the insole can wirelessly and ubiquitously communicate with an adaptable Artificial Intelligence (AI) lifting engine, that can evaluate lifting amounts and correctness. This information will be visualized to the older workers through an application running on their mobile application, a smartwatch, or a discrete wristband or patch (depending on personal and workplace preferences). These immediate notifications will empower the user to avoid and stop problematic lifting situations, thus reducing the risk of developing back pains due to overexertion
