EeonTex Pressure Sensing Fabric
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.
- 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

EeonTex Pressure Sensing Fabric Product Help and Resources
Core Skill: DIY
Whether it's for assembling a kit, hacking an enclosure, or creating your own parts; the DIY skill is all about knowing how to use tools and the techniques associated with them.
Skill Level: Competent - You might need to break out the power tools. Nothing beyond a power drill or rotary tool should be required, but you might have a hard time with just a screwdriver and hammer. Cutting holes into plastic or metal might be required.

4.3 out of 5
Based on 4 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.
Punch Sensor Material
I used this pressure sensitive fabric between to conductive fabric layers as a punch sensor. It easy to cut and handle and works great. I tried to sew this with a sewing machine, but it put too much pressure on the fabric. Had to sew very lightly just on each corner by hand.
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 posted an example project right below your comment.
I am very interested in this product, but I see that it is not available
Is there any way to buy this product?
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?
Sure you can. No restrictions.
Check out the instructable I linked to above.
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.
The resistance between two points on a surface is pretty meaningless. The only meaningful way of describing the resistance of a surface is as the area between two lines. Take two pieces of copper tape and place them perpendicular to each other so that the surface between them is a square (distance between the strips and strip length is equal). Now measure the resistance between the two strips. That's the resistance per square for that surface.
