Our friends at PCB Piezotronics recently published a white paper that explores how haptic technology enhances user experiences by integrating touch feedback into devices such as smartphones, game controllers, and smartwatches.
It examines the challenges manufacturers face in maintaining consistent haptic performance across devices and discusses various testing methods used in production.
Traditional approaches like Laser Doppler Vibrometry (LDV) and accelerometer-based testing are analysed, highlighting their limitations in cost, complexity, and environmental sensitivity.
The paper also introduces microphone-based testing as a cost-effective, non-invasive solution that balances accuracy and efficiency, making it ideal for large-scale production environments.
