The dataset supporting 'Fiber pumps for wearable fluidic systems', published in Science in March 2023. In this work, we present a fluidic pump in the form of a flexible and stretchable tube. These tubes - or 'fiber pumps' - can generate significant fluidic pressure and flowrate without moving parts or vibration. They are intended to be combined with textiles and clothing. This allows high pressure fluidic circuits to be seamlessly integrated into wearable devices, powering soft supportive exosuits, thermoregulatory clothing, and wearable haptics. This dataset contains the characterisation data of the pumps themselves, as well as characterisation data of the demonstrations that incorporate these pumps. Pump characterisation data includes measurements of pressure, flowrate, power density and other pump metrics. Demo characterisation includes measurements of strain, force, thermal transport and other data. A detailed description of the measurements, file types and naming conventions can be found in the read me file included in the dataset.
