Description: This is hot! Literally! Apply 5-12VDC and the stainless steel fibers in this heating fabric will warm up, creating a little heating pad. On one hand, it's just a gigantic resistor. On the other hand, it's flexible, light, and can be wrapped around a project. Originally designed for portable wearable heating pads, this fabric can be used for wearables, weather balloons, DIY-bio projects, thermal cycling for materials testing, etc.

The temperature reached varies with voltage. Note that while the data/spec sheet says 15cm, its more like ~14cm long. Check the spec sheets in the Technical Details tab for a table of voltage/current/temperature outputs. You could PWM it with a power N-channel transistor if you want finer temperature control.

We also have a smaller version of this heating pad
