Prototyping Skweezees: Slipcover

The whole piece of wool, electrodes, cable and foam will be covered by a last layer of material to make the Skweezee objects washable/hygienic, soft and nice to handle. This cover material will be removable from the foamy-Skweezee-with-tail to be more »

Prototyping Skweezees: insulation of the wool

We choose PU-foam because it is easy to cut patterns out of it and sewing these together is also relatively easy. It holds the wool and electrodes together, it is a relatively lightweight and an elastic material. Finally, the foam more »

Prototyping Skweezees: Electrodepatches

We will use ethernet-cable because it has 8 wires inside and it already has a cover/protection for these wires as well. The separate wires are a bit stiff but movable enough for our concept (they will be inside the Skweezee, more »

Skweezee – Obtaining a value (µC)

Skweezee – Obtaining a value (µC) The obtained Skweezee value after the Analog to Digital convertion is in a range of 0 to 1023 (2^10 – 1 –> 10 bit resolution). We want this value to be normalized/scaled to a more »
