Laser-induced graphene sensors made affordable with stencil masking

Researchers at the University of Hawaiʻi at Manoa in Honolulu have unveiled a new technique that could make the manufacture of wearable health sensors more accessible and affordable. Producing these devices often requires specialized facilities and technical expertise, limiting their accessibility and widespread adoption. So, the researchers introduced a low-cost, stencil-based method for producing sensors made from laser-induced graphene, a key material used in wearable sensing. "This advancement allows us to create high-performance wearable sensors with greater precision and at a lower cost," said Tyler Ray, the researcher who led this study.
