Vibrant Composites is an independent guide to haptic feedback technology. It explains how the actuators inside phones, watches, controllers, and car displays produce touch feedback, how that output is driven and measured, and where haptics helps people who can't rely on a screen or a speaker. This site is an independent publication and isn't affiliated with any company of the same name.
What the site covers
The Technology section covers actuator physics, drive electronics, and measurement, starting with a comparison of ERM, LRA, piezo, and tap actuators. The Applications section covers haptics in wearables, accessibility tools, and car interiors. The articles are longer essays on tap-based actuation and tactile language design, written from a hardware-first point of view.
How the guides are written
The guides are written for engineers, designers, and curious readers who want the mechanism explained plainly. Performance figures appear as typical ranges, because real numbers depend on the specific part, its driver, and the product it's mounted in, so check any figure against the datasheet for the part you're using. The guides explain how classes of technology work and don't review, rank, or recommend specific products or suppliers.
A hardware-first view
Many haptic interaction ideas have been proposed that outrun the actuators available to build them. When an actuator can produce clean, repeatable, distinct output, the interaction design problems become tractable, and when it can't, firmware and interface work can only compensate so far. That's why the site starts with the hardware and works outward to the products and the people using them.
