![]() Regarding mechanical design, larger trackpads reach a thickness of around 4 mm. Piezo Components Enable a Thinner Design for Trackpads What makes a piezoelectric trackpad so desirable? There's no single answer to explain the advantages of piezo trackpads, but it can be summed up by the design's simplicity and enhanced user experience.ġ. Overall, haptic trackpads eliminate many issues endemic to other trackpad models, and piezo technology builds on haptics' qualities. When a user presses the trackpad, it senses the force and signals the pad to click. These layers fasten onto a bracket or on the cover. The piezo haptic trackpad has a simple design with three thin layers: glass, touch printed circuit board assembly (PCBA), and piezo haptic touch. However, not all haptic trackpads use piezo technology, which is considered top-of-the-line. Now Windows and Lenovo are following suit, as they've announced the introduction of haptic trackpads in 2021. Then haptics came onto the scene.Īpple began incorporating haptics in their laptop trackpads in 2015. Before that, they were mechanical trackpads. Prior to haptics, most laptop manufacturers used what's known as capacitive trackpads, which detect touch by forming an electrostatic field on the surface. However, as major computer manufacturers continue tweaking current trackpad designs to incorporate haptics, it's become clear that they are here to stay. Some predicted the dawn of haptic technology to be nothing more than a tech trend.
