Calmz
Daily companion for emotional regulation.
What is it?
Calmz is an interactive wearable designed to help students and young adults manage everyday stress and anxiety. Created as a stylish croissant-shaped bag charm, it offers an immediate, screen-free way to pause and regain a sense of calm during stressful moments. Rather than relying on a mobile app, Calmz uses gentle haptic guidance to lead users through a paced breathing exercise that can be performed anywhere, helping them regulate their breathing and emotions with minimal attention or effort.
Each session begins with a long vibration signaling the start of the exercise. Strong rhythmic pulses guide the user's breathing, while smaller vibrations indicate brief breath-holding intervals. The session ends with a gradually fading vibration, gently signaling its completion. By combining tactile interaction with calming sensory feedback, Calmz supports self-regulation and emotional well-being through an intuitive everyday experience.

How does it work?
Calmz is built around an ESP32-S3 microcontroller powered by a rechargeable Li-Po battery, allowing it to operate as a fully portable standalone device. Its soft croissant-shaped enclosure is 3D printed in flexible TPU, while an internal PLA frame securely houses the electronic components. The custom-built hardware integrates a push button, vibration motor, RGB LED, and battery into a compact circuit controlled by embedded C++ software developed using the Arduino framework. The software coordinates the timed vibration patterns and visual feedback that guide each breathing session, creating a seamless, screen-free interaction in a compact wearable form.
