Soft Interfaces is a groundbreaking project that is changing how we interact with everyday objects by merging advanced technology with textiles. The result is a lamp whose brightness can be changed just by pressing or stretching its soft, fabric-covered surface. This is possible thanks to liquid metal embedded within custom-knitted fabrics. The collaboration between the Fraunhofer Institute for Reliability and Microintegration IZM and WINT Design Lab offers a glimpse into a future where touch and movement replace screens and buttons in our daily technology.
The lamp developed by the team stands out for its tactile interaction. Instead of relying on switches or digital displays, users simply touch or stretch different areas of the fabric to adjust the light’s intensity and temperature. This intuitive, screenless control uses body movement and the sensation of touch, creating a direct connection between the user and the device. The lamp’s textile surface is engineered so that when it is pressed or stretched, the cross-section of the liquid metal pathways changes. These tiny shifts are detected by the system and translated into changes in the lighting, making the interaction feel almost magical.

What truly makes Soft Interfaces unique is its approach to integrating technology into fabric. The team developed new methods for injecting liquid metal into knitted textiles, ensuring the pathways are precise and durable. This breakthrough enables the fabric to sense even the gentlest touch, surpassing traditional conductive threads in sensitivity and flexibility. The lamp’s textile screen is held in a specially designed frame that keeps it perfectly tensioned, diffusing light softly throughout the room and hiding the technical components from view.
The implications go far beyond just lighting. This technology could soon transform home textiles into responsive surfaces, make car interiors more interactive, or bring new levels of sensitivity to medical devices. The energy consumption of these textile interfaces is much lower than that of traditional digital displays, offering a sustainable path forward for smart product design. The research teams are already testing further applications and refining the technology for broader use.
Design was central to the Soft Interfaces project. WINT Design Lab worked closely with Berlin-based studio case studies to develop unique knit patterns and yarn blends. These not only define the interactive zones but also enhance the look and feel of the lamp, making it as beautiful as it is functional. The color and texture of the fabric are designed to complement the adjustable lighting, shifting in appearance with the mood of the room.
Soft Interfaces signals a new era for human-object relationships, one where technology is seamlessly woven into our environments. As the research continues, we may soon see textiles that do much more than cover our furniture. They could become the very interface between us and the smart devices in our lives.
