Closed Loop Smart Athleisure Fashion

closed loop smart athleisure fashion is a new initiative based on previous work of Marina Toeters ( and Margreet de Kok (Holst Centre). The smart shirts continuously measures the ladies’ key vital signals based on Holst Centre’s advanced printed sensor technologies on flexible substrates for textile integration. The laminated sensors are truly wearable, comfortable, robust, invisible during use, washable up to 25 cycles, and designed for unobtrusive integration in conventional fashion production.
This new collection targets fashionable sporty ladies at office work and right after work, they embrace forward thinking. The closed loop lease and recycle system make it extra special.

Intelligent Fashion, containing technology that can measure your health, and are still sustainable. My shirt keeps track of my heartbeat and respiration. So I can be more effective.

I know there is a lot of technology in there, but I don’t feel it. The sensors are seamlessly laminated onto the fabric. It’s very comfortable.

It’s beneficial to wear them on a daily basis, because my clothes check my well-being and stress level.

The lease and recycle system is a closed loop. I don’t have to worry about what to do when the garment has no use for me anymore. The technology will be de-laminated from the shirt, and recycled.

It sounds like a dream of the future but it’s right here and we are wearing it.

We are so honoured to announce that the Closed Loop Smart Athleisure Fashion project is chosen as Top 3 Next Tex Innovations: “Together with Munich Fabric Start and FashNerd, we [Sourcebook] thought your work particularly stood out and fits perfectly with what we want to communicate at our Next Tex Innovations Showcase.” Thanks for these nice words Sourcebook! The project will be featured during the Munich Faric Start end of January 2018.
