Personalised Body Sensor Networks with Built-In Intelligence for Real-Time Risk Assessment and Coaching of Ageing workers, in all types of working and living environments

Periodic Reporting for period 2 - BIONIC (Personalised Body Sensor Networks with Built-In Intelligence for Real-Time Risk Assessment and Coaching of Ageing workers, in all types of working and living environments)

Reporting period: 2020-07-01 to 2022-03-31

Only half of European workers aged 55-64 are still in employment today - with strong gender and regional differences. To fight the consequences of demographic change, which puts considerable strain on social security systems, many EU countries have already raised the official retirement age and have often also restricted possibilities for early retirement.

This however can only be achieved if the work is made more sustainable for an ageing workforce, in terms of good working conditions, physical and mental well-being, and work–life balance.

BIONIC is a European research project that developed a mobile, unobtrusive and privacy preserving platform for real-time ergonomic risk alerting and coaching, enabling the design of workplace interventions adapted to the needs and fitness levels of specific ageing workforce. Optimal engagement of the workers is supported by motivating, gamified education elements for prevention and self-management of musculoskeletal health in any working/living environment.

The BIONIC system can be integrated unobtrusively into different types of cloth and can be used by a worker throughout the full working day and at home or in the gym.

The application aim is two-fold

1) to give health related feedback to the user
2) to obtain evidence-based data to medically sound workplace recommendation in any environment.

The BIONIC system is adjustable to the fitness and age of the worker and performs ergonomic monitoring and feedback to the user, e.g. for prevention exercises at home.
The recorded data is completely transparent for the user and can be useful as information source for strain estimation, e.g. by medical staff.


The main objectives of the BIONIC project are:
- Monitoring and prevention of work-related risk factors for the various types of musculoskeletal diseases (MSD) and related disorders.
- Continuous medically sound persuasive and unobtrusive coaching, e.g. for men and women with chronic musculoskeletal diseases


The scientific and technical objectives to reach these goals are:
- Creating an innovative, holistic and unobtrusive body sensor network (BSN) that can be freely and loosely integrated into sportswear, workwear and Personal Protective Equipment
- Allowing for completely mobile real-time and intelligent sensor data fusion and analysis
- GDPR compliant user data management, analysis, presentation and protection
- Kinematic and biomechanical models for age adapted ergonomic risk assessment and workplace analysis
- Gamified user coaching and user interaction
- Validation of the system in a real setting, i.e. at workplaces, home, outdoor activities
The project can be roughly split into three different stages:

Year 1: System design phase
Year 2: System development and prototype implementation
Year 3: Pilots phase and system validation

With a user driven design approach, including questionnaires, and discussion with experts the user requirements, usage scenarios and medical requirements and trust concepts for medical wearables of the BIONIC framework have been defined. In parallel state-of-the-art sensor hardware was reviewed, and a set of sensors was selected. Based on this information and feedback from the end-users a biomechanical model and ergonomic methods for this model (OWAS, ISO11226) were selected. Additionally, a procedure and a mobile application for generating a 3D morphometry of the user was implemented. In parallel to these tasks the platform concept, including data types and categories and all the main components of the system were defined. Once the user and medical requirements were defined the work on the gamification strategies for optimal user engagement started. All previously mentioned achievements were analyzed and aligned with a Privacy and Data Protection Framework.

During year two, the “system development and prototype implementation” phase, different versions of prototypes were implemented to eliminate dependencies between components to obtain an early feedback from the partners. A heterogeneous, time synchronized network application layer software stack has been implemented and tested for the BSN. Possible platforms and concepts for on body processing have been evaluated and a prototype running full body kinematics at 100Hz including carried load estimation from pressure insoles has been developed. Apart from OWAS and ISO 11226 an age adapted ergonomic risk model has been developed and was implemented on the embedded application processor. The data platform including authorization and storage services has been implemented and tested. A detailed report on Data Protection Measures giving extensive analysis of the privacy and security measures for the system has been developed during year two as well.

The last year of the project focused on the pilot phase and the validation / evaluation of the system under different scenarios and environments and continuous improvement of the implemented software stack. It could be proofed, that the developed BIONIC system can be used in a manufacturing and a construction environment. The BIONIC platform solution was provided as a cloud solution for the construction environment and as an on-premises installation for the manufacturing environment. The system was implemented in a way that it could be updated “in field” which allowed the partners to continuously improve the system during the pilots. Apart from the pilot phase in the working environment clinical studies on the newly implemented fatigue algorithm and the use of the gamification app were conducted. The loosely coupled kinematic and processing of the ergonomic methods were evaluated in a laboratory environment.
The BIONIC project focuses on technological and data protection challenges to provide a mobile system that targets widespread usage of (long term) in field mobile ergonomic assessment with objective, reliable and trustable data management and measures as well as interactive feedback.

Advances beyond the state-of-the-art are:

- Magnetometer-free and self-calibrating inertial body motion tracking, i.e. the sensor to body-segment mounting of inertial measurement units can be automatically estimated alongside the human pose tracking, thus allowing for minimal setup time and neglecting error prone calibration phases for inertial body motion capture
- Kinematic estimation from loosely coupled sensors, i.e. the body sensor network can be fully integrated into comfortable clothes and do not have to be tightly fixed on human bones and the obtained kinematic motion estimation generalizes to a wide variety of motions with calibrated kinematic uncertainty estimates.
- Feasibility of long-term completely mobile, online ergonomic assessment, based on human motion capture.
- Modular multi-sensor network that can be easily synchronized and integrated into cloth.
- New approach to trustable monitoring system that is GDPR compliant

The expected impact of BIONIC target to ease the long-term applicability of ergonomic monitoring and assessment in-field for long-term mobile measures that support evidence based medical support and prevention educational with trustable data management. To ensure availability of the developed technology the scientific progress was frequently reported on international conferences, journals and fairs and the technology is available via SMEs.
