Aluminum and nitrogen combine to form the thin film coating known as aluminum nitride (AlN). It is a ceramic substance with good electrical insulating qualities, high thermal conductivity, and chemical stability.
In applications where high-temperature conditions and corrosive materials are present, AlN coating is frequently employed as a protective coating for electronic devices and components.
The high thermal conductivity of AlN coating, which makes it a great choice for use in electronic equipment that generate a lot of heat, is one of the coating’s most important features.
AlN coating can contribute to extending the life of electronic components and enhancing their overall performance by more efficiently dispersing heat.
The electrical insulating qualities of the AlN layer are another benefit. It is perfect for use in high-voltage electronic applications since it has a high breakdown voltage and can endure strong electric fields.
AlN coating is chemically stable and can withstand corrosion from a variety of chemicals in addition to its thermal and electrical qualities. Because of this, it can be used in challenging conditions when other coatings might degrade quickly.
AlN coating is a flexible, high-performance coating that can offer notable advantages in a variety of electronic applications.
Global aluminium nitride (AlN) coating market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
A surface cleaning method created by Cornell allows for the high-quality manufacturing of AlN, maximizing its potential.
Aculon has developed proprietary particle modification coating processes that, through functional treatments, enhance the behavior of AlN particles or powders.
A dense, crack-free AlN coating with a high deposition rate, outstanding adhesion, is available from Heraeus High Performance Coatings.
For the synthesis and deposition of cubic-structured AlN coatings on metallic substrates, suspension plasma spray (SPS) technology is suggested.
Effects of the substrate materials, the nitriding agent, the suspension liquid carrier, and the standoff distance during SPS deposition.
Conformable AlN Piezoelectric Sensors as a Non-invasive Approach for Swallowing Disorder Assessment.
Deglutition problems (dysphagia) are common symptoms of a wide range of conditions and can severely impair the patient’s quality of life.
The clinical examination of this issue entails intrusive screening, the findings of which are subjective and do not give a clear and quantitative assessment. Alternative solutions based on wearable technology have been offered to address these difficulties.
The use of ultrathin, compliant, and flexible piezoelectric patches capable of converting laryngeal movement into a well-defined electrical signal with little anatomical blockage and excellent strain resolution.
The sensor is built on an aluminium nitride thin film produced on a soft Kapton substrate, and it includes an electrical charge amplifier as well as a low-power wireless link to a smartphone.
To assess its effectiveness, an ad hoc constructed laryngeal motion simulator (LMS) capable of simulating the movements of the laryngeal prominence was utilised.
The physiological deglutition waveforms were then extrapolated on a healthy volunteer and compared to the submental muscles’ sEMG (surface electromyography).
Finally, several experiments were performed to evaluate the sensor’s potential to give therapeutically meaningful information.
The dependability of these aspects allows for an unbiased assessment of swallowing capacity, opening the way for the development of a system capable of providing a point-of-care automated, unobtrusive, and real-time extrapolation of the patient’s swallowing quality even during typical behaviour.
The effective evaluation of swallowing quality using an ultra-thin, flexible piezoelectric sensor and its potential usage as a medical device to deliver clinically important information non-invasively.
The AlN-based lightweight sensor was created and designed using conventional microfabrication methods on a thin layer of Kapton, and it was attached to the skin with a coating of adhesive PDMS-PEIE polymer.
When attached to the subject’s neck, its conformable construction, paired with the sensitive and predictable reaction, provides great performances without interfering with the larynx movement’s typical behaviour.
Utilising wireless Bluetooth technology, the output voltage was successfully transmitted to a smartphone after being amplified and filtered by a suitable conditioning system, enabling its smooth usage in therapeutic applications.
Even throughout the course of lengthy testing methods, the sensor was able to consistently produce a reproducible result.
The doctor may assess certain significant aspects, such as the length of the swallowing act, the frequency of spontaneous saliva deglutition, and delay, by using the generated data.
The objective assessment of the subject’s swallowing capacity is made possible by the recording of these aspects, which may also allow for the early detection of pathological diseases.
The potential to develop a system that can automatically and instantly extrapolate clinically pertinent information and to test it in a crucial way to determine its safety and efficacy.
