Piezo vs LRA vs ERM: How to Choose a Haptic Actuator

Piezo, LRA and ERM actuators are the three main ways to create haptic feedback in electronics. ERMs are low-cost motors suited to simple alerts. LRAs deliver crisper vibration near a single resonant frequency and dominate smartphone notifications. Piezo actuators respond fastest, cover the widest...

How Boréas Piezo Haptics Power the Framework Laptop 13 Pro's Trackpad

Framework announced on April 21, 2026 that its Laptop 13 Pro ships with a haptic trackpad built around four piezoelectric discs and a single BOS1921 driver IC from Boréas Technologies. The trackpad has no mechanical hinge, and independent reviews from The Verge, Engadget, and Tom's Hardware all...

What Is CapDrive? The Piezo Driver That Recovers Energy on Every Actuation

CapDrive is a high-voltage piezo driver architecture developed by Boréas Technologies that powers piezoelectric actuators for high-definition haptic feedback while recovering energy on each actuation. By recycling the charge stored in the actuator's capacitance rather than dissipating it as heat,...

Can Passive Cooling Keep Up With Modern Smartphone SoCs? Why Vapor Chambers Are Hitting a Thermal Wall

Smartphone passive cooling uses vapor chambers, graphite sheets, and conduction-based heat spreaders to dissipate SoC thermal energy without moving parts. Even Apple's A19 Pro, one of the most efficient flagship chips on the market, ships in the iPhone 17 Pro Max with a vapor chamber to manage...

Smart Glasses UX: Why Every Input Modality Falls Short

Smart glasses input design is a comparison of trade-offs. Capacitive touchpads, mechanical buttons, voice commands, eye tracking, and neural wristbands each address part of the interaction problem while creating new failure modes — misfires from sweat, single-axis input limits, social friction,...
