In this work, we fabricated a high-performance and biocompatible
porous triboelectric nanogenerator (TENG) with friction layers made
by silk fibroin (SF)@MXene composite aerogel (SF@MXene-A) and a PDMS
sponge. The incorporation of MXene into the SF aerogel increases the
specific surface area as well as the resulting surface charge density,
providing a way for designing a high-performance aerogel TENG. The
TENG with the biocompatible SF aerogel achieves an optimum output
performance at a ratio of MXene to SF of about 1:1, obtaining a maximum
open-circuit voltage (Voc) of 545 V and maximum short-circuit current
(Isc) of 16.13 μA. The Voc of our SF@MXene-A based TENG is about
2–3 times larger than the reported best values of other aerogel-based
TENGs. In addition, owing to the recognized biocompatibility and advantageous
air permeability of the SF@MXene-A, we designed a bioporous TENG mask
that diagnoses asthma symptoms. The SF@MXene-A based TENGs have potential
applications as wearable devices for diagnosing breath-relevant diseases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
