Controlled manipulation of fibers that are as thin as or even thinner than human hair is a real challenge. Despite ...

Abstract: Piezoelectric film sensors can be used to measure pulse wave, but motion artifacts often contaminate the signal, leading to measurement failures. This study proposes a method for estimating ...

Abstract: This paper presents a millimeter-scale piezoelectric effect-based force sensor that uses the change in its resonant frequency as the detection principle for high sensitivity and a wide ...
