This sensor is inspired by the “design” of fish scales and bird feathers: how single elements are repeated, and how it allows the main body to bend smoothly by sliding over the others.
The scale in this sensor is made with Eeonyx non-woven conductive textile. The carbon is infused on non woven textile in order to maintain 20k ohmm per sq. The single scale measures aprx. 10k ohm from one end to the other. The size of the each scale is 3cm by 4cm.
When laying flat, electricity flows through series of scales from one end of the sensor to the other, adding the resistance of each scale. This is similar to potentiometer or slider. When bent inward, the scale touches each other in shorter distance resulting the resistance across to become lower. When bent outward, the scale touches further away, or dose not touch at all, resulting higher resistance or discontinuity.
The reading of this sensor is not smooth, but it gives a unique combination of analog sensor (slider) and digital sensor (contact switch) affect.

The sample consists 9 scales, placed in 1, 2, 3, 2, 1 order, measuring aprox. 50- 60k ohm when laying flat across the whole sensor.
