The use of inorganic-based flexible piezoelectric thin films for biomedical applications has been actively reported due to their advantages of highly piezoelectric, pliable, slim, lightweight, and biocompatible properties. The piezoelectric thin films on plastic substrates can convert ambient mechanical energy into electric signals, even responding to tiny movements on corrugated surfaces of in...

Syringe-injectable mesh electronics with tissue-like mechanical properties and open macroporous structures is an emerging powerful paradigm for mapping and modulating brain activity. Indeed, the ultraflexible macroporous structure has exhibited unprecedented minimal/noninvasiveness and the promotion of attractive interactions with neurons in chronic studies. These same structural features also ...

In this work, Ag nanoparticles (NPs) were fabricated by thermal decomposition of silver nitrate in organic solvents the presence sodium oleate (SOA) and 1-octadecanol (OCD-ol). The effects different concentrations OCD-ol on morphology properties nanomaterials investigated detail. structural analysis showed good crystallinity. TEM images samples that with change fabrication conditions, sizes sha...

This review studied the mechanical behaviors of Glass ceramics (GC) based on Al2O3 /SiO2 system. are great interest due to their wide variety applications, which have ability fulfil recent demands advanced mechanical, optical and biomedical applications. Glass-ceramics typically heat-stable greater features than glasses. In addition, properties can be customized provide variable volume fraction...

This paper reviews the application and operation of integrated sensors and actuators in biological and physiological environments. Integrated transducers are widely employed for invasive and non-invasive patient monitoring, for recording and understanding biological events and systems, for delivery of chemicals and electrical stimuli into the body, and as a means for eventual realization of clo...

Research in recent years has greatly advanced the understanding and capabilities of multi-beam interference (MBI). With this technology it is now possible to generate a wide range of one-, two-, and three-dimensional periodic optical-intensity distributions at the microand nano-scale over a large length/area/volume. These patterns may be used directly or recorded in photo-sensitive materials us...

Nanotubes, nanowires and nanobelts are important one-dimensional (1D) nanomaterials that are the foundation for nanoscience and nanotechnology (Fig. 1a). 1D nanomaterials have important applications in electronics, optoelectronics, sensors, biomedical science, environmental science, green energy and advanced defence technologies. This themed issue on inorganic 1D nanomaterials gathers papers ab...
