Flexible ionic pressure sensors: From migration‐electronic mechanisms to emerging iontronic paradigms

InfoMat, EarlyView.
Mechanisms, materials, structures, and applications of the FIPSs. Abstract Flexible ionic pressure sensors (FIPS) have emerged as promising candidates for bridging the gap between electronics and biologically compatible interfaces. Unlike previous reviews, which focused primarily on materials or devices, this review presents a classification of FIPS ...

Sol‐Gel Coating on CA‐60 Steel Surfaces: A Process for Corrosion Inhibition

Materials and Corrosion, EarlyView.
30% of the steel produced worldwide is used to replace losses due to corrosion. The application of the sol‐gel process to inhibit and delay deterioration appears as a viable methodology for protection against aggressive environments. ABSTRACT The phenomenon of corrosion causes worldwide damage, which is not only economic but also results in the loss of
