The rapid advancement of the Internet of Things (IoT), Artificial Intelligence (AI), and wearable technologies is propelling humanity towards a new era of "unconscious, always-on smart living." As a next-generation platform for human-computer interaction, the smart ring, with its miniaturized design, biological sensing capabilities, and seamless connectivity features, breaks the boundaries of traditional smart devices in various scenarios. Whether for workplace collaboration, health management, family life, or social entertainment, the smart ring provides a complete "scene perception - demand response - service" experience in a lightweight and highly private manner.
Although current smart rings achieve lightweight interaction, their usage still relies on notifications from a paired mobile phone APP. Users must actively check the device to receive information, making it easy to miss critical alerts (such as health anomalies or important schedule reminders) due to neglect or operational delays. Therefore, a proactive interaction system for the device becomes particularly important, with haptic feedback being a key component of such a system.
Awinic's Smart Ring Application Solution
The following is the smart ring solution launched by Awinic Electronics:

Within the proactive interaction system, haptic feedback is controlled by a high-performance Haptic Driver IC. Awinic Electronics, a leader in mixed-signal technology, has received widespread acclaim for its Haptic feedback solutions since launching its linear motor driver IC in 2017. It has become a preferred solution for many mainstream domestic and international manufacturers seeking to enhance the tactile experience of their devices.
Awinic Electronics introduces the high-performance, compact driver AW86235CSR specifically designed for highly integrated smart ring applications.

Gradual
Wake-up Function:
Based on sleep cycle monitoring, it wakes the user with progressively gentle
vibrations during light sleep stages, avoiding the harsh sounds of
traditional alarms that disrupt deep sleep, thus improving morning alertness.
Schedule
& Reminder Management:
Supports synchronization with phone calendars (meetings, appointments, etc.) or
health tasks (hydration, activity). Distinguishes reminder types through different
vibration patterns (e.g., short vibrations for hydration reminders, long
vibrations for important schedule alerts).
Context-Aware
Vibration Design:
Vibration intensity and frequency can be customized. Supports a "fingertip
whisper" mode for silent environments, balancing privacy and convenience.
Power Supply & Battery Management Module Features Multi-Layer Protection Design:
The AW32012CSR Lithium Battery Charging IC supports USB specifications and power path management, suitable for 3.7V lithium batteries.
The AW37030D110DNR LDO IC provides a high-performance 300mA regulated output to power core components.
The AW33901FCR Over-Voltage Protection IC protects downstream circuits with its low 30mΩ on-resistance and fast 50ns shutdown characteristic.
Sensor Module Enriches User Experience:
The AW86872CSR Button Detection IC achieves precise press recognition with 14-bit resolution and low power consumption.
A high-performance switching Hall effect sensor easily enables in-case detection.
