Introduction
Thermal components in classical hardware development were in many cases regarded as passive components. Heat sinks and fan were late additions to the design with little care to performance. Their function was simple, remove heat when needed. This assumption is not valid any longer in the piezoelectric age. Piezoelectric cooling is not passive. It is an actively controlled system which relies on material behaviour, electrical driving conditions and mechanical resonance working together. Without coordination, there is a lack of efficiency and reduced reliability.
With many years dedicated to the development of piezoelectric technology, Bestarsensor specializes in providing Integrated Solution of Piezoelectric technology, solving complex problems, such as Customized Piezo Ceramics, Piezo Fan Driver Design Optimization, Piezo Cooling​ Solutions. These capabilities are based on deep expertise in the field of Sensors & Actuators so as to provide a practical, system-ready set of cooling architectures instead of isolated components. For you, this means one thing clearly. You do not receive a one piece ceramic part, you get a validated and deployable piezo cooling system.

The Barriers to Entry of Piezoelectric Cooling
Piezoelectric cooling has obvious benefits. These include silent operation, low power consumption and ultra-thin form factors. However, there are some practical barriers when it comes to implementation from a technical standpoint.
The first problem to get through is driving waveform consistency. Piezo devices have to be used near their resonance frequency. Small deviations will cause less displacement and less airflow. Larger deviations may cause damage to the ceramic element.
The second challenge is power loss control. Poorly created driver circuits create needless heat. This makes systems less efficient and achievable when it comes to actual cooling out in the real world.
The third challenge is the acoustic behavior. Mechanical vibration will introduce unwanted audible noise if there is not an alignment of structural and electrical parameters.
These challenges account for the difficulty of piezo cooling without system-level expertise. Bestarsensor solves this by solving the impedance matching of ceramics and electronics in advance. Customers need not become experts in piezoelectric physics to use piezo cooling.

The Dual Edge of Bestarsensor: Products and Solutions
1.Piezoelectric Products with Exceptional Performance
Every good system we know of begins with stable materials. Bestarsensor offers piezoelectric ceramics that have high piezoelectric coefficients, high operation life and good consistency in performance. These ceramics have predictable behavior at high temperatures with prolonged operation cycles and different environmental conditions.
Material development is informed by experience acquired in applications of both senses and actuation. This dual-domain knowledge is what enables Bestarsensor to control responsiveness, durability and efficiency at the material level.
2.End-to-End System Support
The value of Bestarsensor is not limited to materials. Bestarsensor will develops piezo fan and actuator layouts in accordance with customer structures and airflow paths.
3.Design and Control of the Driver Reference
Complete drivers reference designs are provided. These include circuit schematics and control strategies to keep the system in a state of resonance operation and power loss to a minimum.

Why Solution Capability Is Not Negotiable
There is risk involved in selecting piezoelectric cooling components that are not supported by a system level approach. Improper circuit matching will cause a cracking of the ceramic or unstable vibration. Poor mechanical integration may lead to poor airflow efficiency. These issues emerge late in the development cycle in many cases and are the most costly to design at this stage. Bestarsensor minimises these risks using a system optimisation.  Time to market is another benefit. With validated reference designs, we brief the time of product development. This acceleration is important in competitive electronic markets.

Conclusion
Thermal management has entered a system driven world. Performance is no longer defined by materials in and of themselves. This is dependent upon how materials, electronics and mechanics interact.
With the long-term experience in piezo electric Sensor&Actuators, Bestarsensor is not just a providers of components. We offer integrated, reliable and scalable cooling solutions which are designed to meet the needs of real-world products.
