Smart2Go aims at the creation of a pre-standardized, universal, autonomous, scalable and flexible energy-supply platform for a wide range of products and application scenarios of wearable electronics.

This aim will be achieved by the combination of a powerful, thin and scalable battery with appropriate energy harvesting technologies. Each unit will be capable for a storage capacity up to 110 mWh (10 cm² area). All the performances will be retained after bending. Two generations of single layer pouch prototype cells with a nominal capacity of 60mAh are already produced by VARTA Micro Innovation, using semi-industrial equipment. The two generations only differ in the overall cell thickness (GEN1: 436µm, GEN2:399µm). With GEN1 cells an excellent cycling behaviour can be achieved. After 500 cycles a capacity retention of 83% was measured. The prototypes will be further investigated and represent one of the key components of the Smart2Go energy supply platform.

The project will also develop ultrathin and lightweight films that will provide protection against environmental and mechanical impacts, handling and radiation. A roll-to-roll manufacturing process for the integration of all the components into the Smart2Go energy supply platform will ensure suitable production capacity with low manufacturing costs.

The performance of the Smart2Go energy supply platform will be demonstrated in two application cases: (1) sport equipment integrating Smart2Go platform and pressure sensitive array and (2) safety garment integrating Smart2Go platform and lighting technologies (OLEDs). They represent a challenge for the demonstration of the Smart2Go platform reliability in extreme environment (i.e. cold temperature, snow, rain, etc.) and a proof of the technical feasibility of the Smart2Go solutions.

Smart2Go project has a duration of 36 months, please, stay updated about the upcoming project results!
