Smart wearable devices for motion detection
Summary:
An Italian Research Institute developed a data acquisition and processing platform on flexible substrate to interface physical sensors (e.g. strain gauges) together with commercial ones (inertial, others), with the final aim to design and fabricate smart wearable devices. R-Y-D partners are sought to develop strain sensors and SMEs in the field of textile electronics to further advance the platform with a textile-based Printed Circuit Board, under technical or research cooperation agreements.
Description:
The Research Institute has a long expertise in flexible electronics and physical sensors. Such technologies result key elements to design and fabricate smart wearable devices.

The team is composed by physicists and electronic engineers with expertise of microelectronic processing (with important focus on flexible electronics), electronic engineers with electronic design skills and advanced coding skills (Smart interface, machine learning, pattern recognition, etc.)
The platform provides sensor fusion algorithms for advanced motion detection (gesture, 3D orientation, etc) It can be used effectively for:
- gesture recognition, through the use of machine learning algorithms
- human machine interface, to use instrumentation or machines remotely with just the movement of hands
- rehabilitation, using the data to track muscular activity or the correct movement of a specific body part
- health monitoring, implementing sensing of vitals (blood pressure, heartbeat, etc.)

Actually the platform is in the form of a wristband with embedded Inertial Measurement Unit (IMU) and strain sensors. The shape and use can be adapted for other body parts. The band is made both of a rigid part (with computational and data tx/rx electronics embedded) and a 100um flexible dual layer Printed Circuit Board (PCB) where the sensors can be integrated. The embedded strain sensors are elastomer based and offers stretchability up to 50% (under development to increase stretchability and sensitivity). Polyvinylidene fluoride (PVDF) piezocapacitors on ultraflexible substrate of PI can be integrated for pressure detection (d33 up to 50pC/N). A 9 DoF (Degree-of-freedom) inertial unit is on the main board to provide 3d orientation and speed data of the wrist. A software has been developed for the management of the calibration of the sensors and data acquisition/processing.
Main innovative aspects are enhanced wearability, ad-hoc design of flexible sensors, low power consumption.

The research group is looking particularly for Research -Y- Development collaborations for innovative strain sensors and for SME in the field of textile electronics with the purpose to further advance the platform with a textile-based Printed Circuit Board (differently from the Polyimide one they are using right now).



Advantages and Innovations:
Due to the high degree of flexibility and/or stretchability that can be obtained with this sensing technology, the Institute is able to achieve enhanced wearability with limited hindering of movements. The platform has been optimized to support physical sensors but it is not limited to them. Virtually any sensor (commercial or custom) can be integrated with few modifications of the schematic. The platform is able to guarantee several hours of continuous stream thanks to the Bluetooth Low Energy Connection IC (Integrated Circuit) embedded and several hardware and firmware optimizations designed.
3D orientation of the tracked part (arm, limb, wrist) can be calculated thanks to 9 DoF (Degree-of-freedom) IMU embedded in the system.

Partner sought

Type and Role of Partner Sought:
The Research Institute is looking for large companies, SMEs, Academic partners, R-Y-D institutions interested in developing sensors, mostly, but not limited to human health monitoring and motion tracking to enable new applications of the wearable device in the field of health-care (rehabilitation, remote medicine, etc.) or human machine interface.

Specifically, but not exclusively:
- R-Y-D partners are sought to develop strain sensors,
- industrial partners are sought under technical cooperation agreements in the field of textile electronics to further advance the platform, providing facilities to realize a textile-based Printed Circuit Board in which electronics, circuits and more sensors can be embedded by the Institute.

The Institute is also considering to collaborate, as a third party or as a partner, in H2020, EUREKA or EUROSTARS projects.
