Memory Fiber offers "Electronic Textile" option

Researchers are committed to the combination of electronic products and textiles for intelligent textile innovation research and development. A wearable electronic textile product has successfully developed a new type of memory fabric that can retain more than 100 days of data.

Meyya Meyyappan and Jin-Woo Han, director of the Nanotechnology Center at the Ames Research Center at NASA, have successfully developed fabrics that are tightly interwoven with copper and copper oxide wires.

A nanoscale platinum film (dab) is placed on each interwoven joint of such a fabric, and at each intersecting “sandwich” structure, a copper wire and a platinum layer constitute an electrode. Above and bottom, a resistive memory circuit is formed.

As stated in the AIP Advances journal of the American Institute of Physics, this innovative technology can be easily introduced into textile products because the nanotechnology naturally forms a staggered memory structure at the fiber intersection.

The copper wire diameter of the prototype design is only millimeters, but the smaller diameter wire will allow increased storage density and reduced weight. In practical applications, electronic textiles must incorporate battery or power generators, sensors, calculators, and storage structures.

Integrate nanoelectronic technology with textiles to form electronic textiles that can observe biomarkers for various diseases and monitor vital signs (pulse, respiration, body temperature, blood pressure, etc.) of elderly people or workers in harsh environments. ), and then transmit the data to the doctor.
