find your sensor

Year of Invention: 2017
Description: The swatch is the result of the idea to use a printed detail giving tactile orientation on an e-textile surface to find a sensor underneath.

One part of the swatch is a simple button as an example of a surface-activated sensor. On top of the button is the top fabric. The tactile orientation is a printed shape, guiding the finger to the area where the activation part of the button is placed.

The study includes considerations of shapes for other sensors (figure 1 – 3 ), placement and substrate materials and is a continuation of the ‘e-textile user interfaces’ project.

Materials: Fabric, Spacer Fabric, Conductive Fabric, Polyester Taffeta/PA Ripstop, Kappamid CSFV
Techniques: Sewing, Heat Pressing, Screen Printing
Dimensions (in cm): 7*10cm

1/ Screenprint the graphics which will guide the interaction. Mind the space between the prints

2/ Cut all pieces of thick fabric approx. 8cm x 9cm

cut all spacerfabric approx. 7cm x 5cm, cut a hole in the center (diam. 5mm)

3/ Iron sewfree adhesive film onto the conductive fabric. Cut into stripes of approx. 5cm length

iron them onto the thick fabric parallel to and centered between the short sides, starting at on egde.

4/ Sandwich the layers thick fabric, spacerfabric, thick fabric. Check if your button works before closing the seam.

5/ Check where exactly the point to press the button is (should be in the center) and compare with your print.

6/ Attach your printed detail, placed above the activation point, on one side. The print should be directed to guide from that side.
