MONOSCALE

We want to own and consume without limits. But what ­approach prevents products such as electronic devices from having a large ecological footprint? One possibility is to use a monomaterial that replaces electronic functions by material-immanent properties. This is how the idea of a kitchen scale was developed. The shape of monoscale allows the residual stress of the material to be used as a measure: The more the scale is loaded, the more it deforms, which is indicated on the scale in grams. The material used is PETG, a polyethylene terephthalate (PET) modified with glycol, which is characterised by high viscosity and impact strength. It can be bent at any angle without breaking. Also, it complies with food safety standards to be used in the kitchen. The monoscale can be produced by injection moulding. This allows it to be manufactured in a single piece in a very cost-efficient way.
