    interesse = inter as ‘between’ + esse as ‘be’ = to be between

    Interested sensors are sensors expressing their interest in things without knowing in advance why the things are of interest.
    The process of making and using the sensors is the act of discovering what is interesting.
    Interested sensors are made by crocheting a meshwork of electrically conductive yarn with varying electrical resistance between two things. The electrical resistance varies depending on forms of stress (stretch, pressure, twist, bend, squeeze…). Interested sensors are crochet because this technique is highly mobile, customizable and handmade, meaning interest can be expressed wherever you are, between all kinds of things and requires you to use your hands and let you mind wander while you make.

    Point of Interest etextile sensor swatch

    The point of interest (POI) of an interested sensor lies between two variable resistors, creating a potential divider. The potential at the POI pans toward either extreme (+ or GND) when the sensors are strained individually, and remains centered when both sensors are strained equally.

    Put in other words: Interested Sensors are pairs of variable resistors where the POI lies in between them. When the resistance of only one sensor decreases (or increases) the voltage at the POI is pulled one way or another. When both resistances change at the same time, the POI stays pretty much the same.

    The example shown in this swatch is of two crochet bend/pressure sensors that can be worn on two adjacent finger knuckles.
