Although only a few 2D materials have been predicted to possess ferroelectricity, 2D
ferroelectrics are expected to play a dominant role in the upcoming nano era as important …

Nanomechanics has brought mesoscopic physics into the world of vibrations. Because
nanomechanical systems are small, fluctuations are significant, the vibrations already …

The auditory system is the most efficient and straightforward communication strategy for
connecting human beings and robots. Here, we designed a self-powered triboelectric …

Piezoelectric microsystems are of use in areas such as mechanical sensing, energy
conversion and robotics. The systems typically have a planar structure, but transforming …

Continuous tuning of material properties is highly desirable for a wide range of applications,
with strain engineering being an interesting way of achieving it. The tuning range, however …

We report an innovative, large-area, and self-powered pressure mapping approach based
on the triboelectric effect, which converts the mechanical stimuli into electrical output signals …

Mechanical interactions are fundamental to biology. Mechanical forces of chemical origin
determine motility and adhesion on the cellular scale, and govern transport and affinity on …

Back in December 1959, future Nobel laureate Richard Feynman gave a visionary and now
oft-quoted talk entitled “There's Plenty of Room at the Bottom.” The occasion was an …

Nanoelectromechanical systems (NEMS) resonators can detect mass with exceptional
sensitivity. Previously, mass spectra from several hundred adsorption events were …

Piezoelectric nanogenerator (PENG) was first introduced by using piezoelectric nanowires
for converting tiny mechanical energy into electric power. 1 Research in nanogenerators has …
