Measuring haptic energy consumption
A smartphone, smart-watch, and fitness tracker are all portable battery-powered systems that can use haptics. Many engineers may be concerned with the energy consumption of haptics in battery critical applications. The DRV2605 and DRV2667 are haptics drivers that can enhance the user experience with haptics, while at the same time minimizing energy consumption.
This document introduces three types of actuator technologies, explains how to measure energy consumption, and compares each type of actuator.
