Energy-Aware Model-Driven Development of a Wearable Healthcare Device

The healthcare domain is experiencing an expansion of wearable embedded devices. These devices are typically battery powered and expected to deliver a safe and reliable service to the patient regardless of its power reserves. Being energy efficient brings an additional level of complexity to the development of these solutions. In this paper we propose the application of a well-founded model-driven energy-aware approach to tackle the energy consumption in such solutions addressing all their critical subsystems: control software, communication and mechanical components. The approach enables exploration of the design space, reduces prototyping costs and helps in build confidence in the proposed solution. We demonstrate this approach in a case study focused on the development of an intelligent compression stocking to treat leg-venous insufficiency. We also discuss how this approach has benefited the development of the actual device.
