The manufacture of flexible electronics that exhibit the durability necessary for use on fabric substrates has always been a challenge. Wearable circuitry needs to exhibit an appropriate flexibility, durability, and adhesion to fabric substrates to be useful, yet present techniques rely on adhering electronics to fabric surfaces through resource-intensive processes that result in relatively delicate products with limited usefulness.

Researchers at Purdue University have developed a single-process manufacturing method, similar to 3D printing, which enables the rapid manufacture of wearable electronics at a fraction of the cost. This method prints flexible sensors into a fabric substrate resulting in embedded sensing devices with dramatic increases in sophistication and resilience. This discovery extends to the production of multi-material sensors in a single manufacturing step, sets the stage for the next generation of wearable electronics with greater sensitivity and durability, and leads to the possibility of many new, more capable applications.
