Here we present a robotic vocal apparatus incorporating a tongue body that is moved by stepper motors under computer control. The vocal tract consists of a central mouth region with a 2-dimentional tongue, a lip section and a nasal cavity. Movement of the articulators changes the vocal tract cross-sectional area, and thereby its acoustic properties, thus providing a means to generate different ...

printing and packaging industries make three phases of solid, liquid and gaseous contaminants which can cause very dangerous problems. the presence of alcohols, inks, and cleaners can result in massive range of industrial pollutants. always respiratory problems, fatigue, dizziness, weakness, abnormal behavior, memory impairment, insomnia, loss of appetite, and impaired vision and hearing and ca...

The emergence of bioprinting in recent years represents a marvellous advancement in 3D printing technology. It expands the range of 3D printable materials from the world of non-living materials into the world of living materials. Biomaterials play an important role in this paradigm shift. This Special Issue focuses on biomaterials and bioprinting and contains eight articles covering a number of...

3D printing has been hailed as a game changer in the manufacturing sector, with major imprints across multiple domains. Players from several industries are investing heavily in 3D printing, with the possibility of extending its applicability to daily use products coming to the fore. With speculation and limited information blurring the line between reality and fiction, it is critical to analyze...
