EU supports an ambitious project for brain machine body connectivity. The B-CRATOS project aims at creating the first battery-free high-speed wireless in-body communication platform for Brain-Machine-Body connectivity

The B-CRATOS project aims at creating the first battery-free high-speed wireless in-body communication platform for Brain-Machine-Body connectivity. Highly ambitious, this collaborative undertaking merges expertise and cutting-edge technologies from the fields of novel wireless communication, neuroscience, bionics, AI (artificial intelligence) and sensing.
As part of the four-year B-CRATOS “Wireless Brain-Connect inteRfAce TO machineS” project, researchers will be developing wireless body area networks (WBANs) with the aim of connecting the nervous system with signalling systems to stimulate various functions, primarily in prostheses. However, in the long-term, the goal will be to do the same even in muscles and internal organs. This will be achieved through the use of chip implants in parts of the body that need to communicate.

B-CRATOS has a budget of approximately EUR 4.5 million and brings together seven partners from higher education institutions, businesses and institutes across Europe. Among the participants is The BioRobotics Institute, Scuola Superiore Sant'Anna, based in Pisa that specializes in robotic arms that can be controlled using brain signals. These brain signals will be captured by electronic chips that will be manufactured by a project business partner. Another partner will use AI and high-performance data computing facilities to map neural patterns in combination with motor control. A fourth partner will make modules that can wirelessly transport data and power to implanted devices in the brain. Uppsala researchers have developed a technology that involves enclosing the microwave signals in the slender space between the skin and the muscle layer. This natural fat layer encapsulates the signals while simultaneously allowing them to propagate. Thus, the device is able to transmit at frequencies as high as 5.8 gigahertz over distances of around a meter. Finally, a German partner will validate this new technology in tests with non-human primates.

B-CRATOS will overcome major challenges relating to power consumption, batteries, and data transmission bandwidth by developing a breakthrough with battery-free bidirectional wireless communication technology. The revolutionary signal-bridge technology will impact healthcare, quality-of-life, human cognition. Key Enabling Technologies for this closed-loop functionality include ultra-low-power ASIC brain implants with read/write capability, in-body battery-free high-speed wireless communications systems and human-like artificial sensors and limbs.

Robin Augustine, B-CRATOS coordinator, said “In the past, we worked with surgically implanted medical devices connected to the Internet. However, the idea is that these systems will communicate without involving an external computer. For example, the prosthesis can function as a spoon that you are conscious of using. But you never feel like it is part of your body, because it is not cognitively integrated into the brain’s processing system. Instead, we want to create a direct connection between a person’s artificial arm, leg or other body part and their brain so that it can sense its presence and experience control over this body part. This requires an implant in the brain.

This project has received funding from the European Union’s Horizon 2020 research and innovation programme under Grant Agreement No. 965044.


About the B-CRATOS Partners

Uppsala University, B-CRATOS coordinator, is a research university in Uppsala, Sweden. Founded in 1477, it is the oldest university in Scandinavia. It ranks among the world's 100 best universities in several high-profile international rankings. The university uses "Gratiae veritas naturae" as its motto and embraces natural sciences. Uppsala belongs to the Coimbra Group of European universities and to the Guild of European Research-Intensive Universities. The university has nine faculties distributed over three "disciplinary domains". It has about 50,000 registered students and 2,300 doctoral students. Of its turnover of SEK 7.4 billion (approx. USD 870 million) in 2020, 29% was spent on education at Bachelor's and Master's level, while 70% was spent on research and research education programs. Uppsala University is involved in a total of 236 projects in Horizon 2020, of which we coordinate 16 of these granted projects (until May 2020). In addition, we are currently involved in five projects under other Directorate Generale under the commission. With a total workforce currently comprising about 40 active scientists, the Division of Solid-State Electronics, Department of Electrical Engineering, Uppsala University, has three major focus areas: Electronics for Life Sciences and Medical Technologies, Electronics for Brian-Inspired Computing and Energy-Efficient Electronics. The goal is to develop technical solutions from individual units to small systems, often starting from novel material and device solutions. We strive for innovations related to electronic sensors, biomechatronics, neuroprosthetics and medical systems for continuous and real-time health monitoring. We also invest in energy conversion and electricity generation to operate small self-supporting sensor systems. The technological base for our research is thin-film technology, semiconductor processing and semiconductor device technology using the in-house state-of-art cleanroom facilities, supported by device and process simulation as well as electrical and optical characterisation. For the Life-Science Technologies aspect, our research objective is to develop technological solutions, from devices to small systems, for comprehensive analysis of genome, proteome, and transcriptome signatures of individuals, thereby enabling AI assisted predictive diagnosis and preemptive therapy. For the Medical Technologies aspect, we strive for innovations such as near-body-network systems, point-of-care electronic sensors, and battery-free wearable and medical systems for continuous and real-time health monitoring.
