Smart Sensing and Smart Connectivity: A Dual-Function Ceramic Component Integrating Sensing and Wireless Transmission
Introduction
With the rapid advancement of smart wearables and wireless communication technologies, products are expected not only to offer a higher level of functional integration, but also to provide real-time feedback and intelligent connectivity. Unictron has introduced a dual-function piezoelectric ceramic component that combines smart sensing with Bluetooth antenna technology, enabling both pressure detection and wireless connectivity within an extremely compact space. This innovative design allows devices to sense user actions in real time and respond accordingly, creating a more intuitive and intelligent human-machine interaction experience.
Piezoelectric Ceramic Sensing Principle
Piezoelectric ceramics generate voltage signals when subjected to force, enabling the conversion of mechanical input into electrical signals. Unictron’s piezoelectric sensing component offers high sensitivity and fast response, allowing it to detect different levels of press or touch input in real time and convert them into stable electrical signals. This enables devices to recognize user interactions more intelligently, including light touch, long press, and sliding gestures.
Integrated Wireless Communication Function
To enable intelligent connectivity, the component also integrates a high-efficiency Bluetooth antenna covering the 2400-2484 MHz band, with radiation efficiency of 44-49% and peak gain of 2.1-2.7 dBi. Through this integrated design, sensing signals can be transmitted in real time to the main control system or paired device, giving the product stable, low-latency wireless connectivity. Whether used in smart earbuds or wearable devices, it can maintain reliable communication performance.
Miniaturization and Packaging Advantages
The component measures only 5.0 × 4.0 × 0.25 mm, representing an approximately 75% reduction in size compared with conventional designs. By adopting SMD surface-mount packaging technology, it not only improves assembly precision and product consistency, but also greatly enhances mass-production reliability. This miniaturized structure gives product designers greater flexibility and allows seamless integration into a wide range of smart wearable devices and wireless modules.
Test Results and Application Demonstration
Using a premium TWS Bluetooth earbud from a well-known commercial brand as the test platform, the component supports multiple touch and force-sensing functions, such as single-tap play/pause, double-tap track switching, triple-tap previous track, and long-press noise-cancellation mode switching. Test results show that the ADC reading exceeds ±1000 counts, meeting the usage criterion of greater than ±800 counts. This demonstrates that the dual-function piezoelectric ceramic component can provide both stable sensing and efficient connectivity in smart interaction scenarios.
Conclusion
Unictron’s dual-function ceramic component is not only a sensor, but also a key enabling device that combines perception and connectivity in smart products. Based on piezoelectric ceramic technology, it integrates sensing and wireless functions to help smart wearables, audio devices, and IoT products deliver more intelligent interactive experiences within an extremely compact form factor. Looking ahead, Unictron will continue to advance material innovation and integration design, bringing smart sensing and smart connectivity technologies to a wider range of applications.
