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,...

Datacenter Cooling Principles, Pocket-Sized Form Factor: Solving Thermal Throttling in Edge AI Devices

Thermal throttling in compact devices is a performance limit triggered when a mobile processor's sustained heat output exceeds what passive cooling can dissipate, forcing a reduction in clock speed. Edge AI is accelerating this problem fast — not because compact devices are approaching...

The Battle for Smart Glasses' Killer App: Why Input Method Will Determine the Winner

Smart glasses are drawing the kind of investment that once went into smartphones, with Meta, Google, Samsung, and newer entrants like XREAL, Snap, and Brilliant Labs all racing toward a mainstream product. Most of that competition plays out over cameras, displays, and AI features. None of it...
