Energy efficient digital architectures for sensor fusion


Radio communication remains the primary battery consuming activity in wireless systems. Advances in MAC protocols have enabled significant lifetime improvements, but in systems with low data rate, idle listening, and other communication artifacts can begin to dominate costs. One proposal to combat this is the addition of a second, extremely low power radio component that is always-on.

Ultra-low power architectures for always-on vision nodes. We are building an energy efficient digital architecture to exploit low-power multi-cores platforms (i.e. programmable PULPv3 platform) in combination with imagers consuming microwatts to enable wireless applications for the Internet of Things, requiring computational power and mobility. In cooperation with other research unit at FBK and external partners.

E3DA cooperates with Motorialab on its work to make sport more safe and entertaining by adding wearable technologies and sensors to equipment and to the end-user. E3DA works having in mind energy efficiency to ease technology mantainance in terms of lifetime, but also we help Motorialab in make technology smarter and smarter and capable to connect wirelessly to any device. Using Motorialab platform we connect wearable/sensor to mobile devices to achieve apps and collect data on user behavior, performance, etc.

This project focuses on the challenges of natural interaction modalities for EMG-powered hand prosthesis. In particular, we are invetigating on an implementation suitable for an embedded system, based on Support Vector Machine (SVM). The work falls within a cooperation with INAIL, Prosthetic center in Vigorso (Budrio, BO, Italy), one of the main prosthetic centres in Europe.

Main activity

Energy efficiency for embedded systems is one of the main research challenges, particularly in last years where the pervasiveness of smart, tiny low cost electronics is enabling ambient intelligence scenarios. Wearables systems, mobile computing and  wireless sensor networks (WSNs) are typical examples of technologies that are gaining increasing attention from both the research community and actual users.
