The rapid and efficient development of soft active materials requires readily available, compact testing equipment. We propose a desktop-sized, cost-efficient, and open source radial stretching system as an alternative to commercially available biaxial and uniaxial stretching devices. It allows for doubling the diameter of an elastomer membrane while(More)
Science presents not only intellectual but also fi nancial challenges. [ 1,2 ] Laboratory equipment in particular is expensive and usually requires large investments—a serious problem in current research with limited fi nancial resources. Building opensource and customized hardand software is a relatively new trend which enables the development of scientifi(More)
While adhesiveness is required for polymer surfaces in special applications, tacky surfaces are generally undesirable in many applications like automotive interior parts. The tackiness of polymer surface results from a combination of composition and additivation, and it can change significantly in natural or accelerated ageing. Since there is no(More)
