Carbon nanotubes (CNTs) have attracted great attentions in the field of electronics, sensors,
healthcare, and energy conversion. Such emerging applications have driven the carbon …

Traditional sound sources and sound detectors are usually independent and discrete in the
human hearing range. To minimize the device size and integrate it with wearable …

Thermoacoustic (TA) effect has been discovered for more than 130 years. However, limited
by the material characteristics, the performance of a TA sound source could not be …

Most mute people cannot speak due to their vocal cord lesion. Herein, to assist mute people
to “speak”, we proposed a wearable skinlike ultrasensitive artificial graphene throat (WAGT) …

MXenes have attracted great attention for their potential applications in electrochemical and
electronic devices due to their excellent characteristics. Traditional sound sources based on …

Acoustic devices are widely applied in telephone communication, human–computer voice
interaction systems, medical ultrasound examination, and other applications. However …

Advances in nanomaterials over the last decade have enabled the practical exploration of
the “thermophone” concept based on a thermoacoustic (TA) mechanism. By applying an …

A novel integration of three-dimensional (3D) architectures of near-field electrospun
polyvinylidene fluoride (PVDF) nano-micro fibers (NMFs) is applied to an intelligent self …

We built a thermoacoustic loudspeaker employing N-doped three-dimensional reduced
graphene oxide aerogel (N-rGOA) based on a simple template-free fabrication method. A …

In this study, we present a copper nanowires (CuNWs) based spray deposition process for
the fabrication of transparent heaters and thermo-acoustic loudspeakers. We developed a …
