Description: This EeonTex fabric is a conductive, nonwoven microfiber with piezo-resistive functionality for use in dynamic sensors to map and measure pressure, bend, angle stretch and torsion. Each sheet of the EeonTex Pressure Sensing Fabric is pre-cut into 12 inch by 13 inch sheets about 0.8mm thick. This fabric is unique and perfect for anyone interested in wearables and e-textiles.
EeonTex Pressure Sensing Fabric is highly conductive with a surface resistivity of 2K Ohm/sq. Additionally, it features a dynamic range of 5g to 100kg, as well as a data acquisition rate of 500 cycles per second.
Features:
- Dynamic Range: 5g–100kg
- Data Acquisition Rate: 500 cycles per second
- Density: 170g/m²
- Thickness: 0.80mm
- Sheet Size: 12"x13" (304.8 x 330.2mm)
- Surface Resistivity: 2K Ohm/sq

4.3 out of 5
Based on 3 ratings:
Very very good
Worked as described, just remember the resistant is determined by the length.
Very sensitive...
maybe too short range of responsivity, as for my needs.
I honestly haven’t had a chance to try this fabric out yet, but given how difficult it was to get a hold of (only sold wholesale) up until now, I am ecstatic that it is being sold on sparkfun.com, and thank you thank you thank you for retailing it.
This stuff looks very interesting but much more information please, maybe a sample project? Plus the data sheet that you link to says nothing useful at all.
Can you cut it into small pieces? What interface?
I am thinking about using it for an array of button sensors for a midi controller.
I wrote an instructables using this material. If I get around to it, I’d like to add instructions for a more basic version, but you can get an idea of how to work with this stuff here: http://www.instructables.com/id/ETextile-Electronics-Differential-Pressure-Sensor/
Hi all!
Can I cut this into smaller pieces? If yes - any important instructions?
I just got this, and when I connect a strip (about 1cm x 5cm) of this to a multimeter and check the resistance, the values seem to change even when nothing else is touching it. And when I turn the multimeter on and off, the resistance is very different, at least 5K ohms difference. Why is this happening and is there anything I can do to fix it? I plan to use a voltage divider and connect it to an Ardulno. Maybe that will fix the problem? Thanks.
