High-end body monitoring & wearables for environmental awareness

Developed with the help of Bear Creek Mining S.A.C. in Peru we developed NazcAlpaca, an innovative training system to avoid work related stress issues. Paired with an app that has adjustable settings, the body-monitoring NazcAlpaca shirt stores data over time to create a training system that’ll help wearers fight stress. It will guide you through the initial body monitoring setup, and even encourages you to stay active. As part of the collection to bring awareness about environmental data, two scarfs can measure the air quality and temperature around the wearer.

Combining alpaca yarns with wearable technology

NazcAlpaca is researching how to combine the high quality of alpaca yarn with highly innovative wearable technology. Electrical components, silver fiber and alpaca yarn are brought together to become an interactive fashion item. A brand identity and 3D-printed casings make sure to achieve a unique look and perfect fit of hard and soft materials. A male and a female version of the body-monitoring garment are made. Via tiny magnets the hardware is connected. An adjustable breathing sensor and hart-rate sensor are knitted in the garment. The NazcAlpaca app will guide you though your body monitoring and enables you to start exercising.
