Wearable Particulate Capturing Device
Master’s Individual Final Project
Project Duration: 5 months
Team Size: Individual Project
My Responsibilities: Electrical Engineering, Mechanical Design, Embedded Systems, Circuit Design, Prototyping (silicone moulding, soldering, 3D printing, laser cutting), Coding (Arduino IDE), Wearable Design, Product Design, Primary Research and Interviews, User-Centric Design, Context Exploration, Iterative Development, Validated Product Delivery.
Nulla is a wearable electrostatic sleeve that captures harmful paint particulates in real-time — without disrupting workflow. Using decorators’ natural hand movements and airflow patterns, it passively traps microplastics directly at the source, where sanding and scraping release them. Nulla is lightweight, cordless, hands-free, and ergonomically worn on the back of the hand.
Every day, every decorator/paint worker unknowingly releases up to 48 tablespoons of toxic microplastics through sanding and scraping—an unavoidable to remove old layers of paint before applying a new coating. With over 164,000 tonnes of pollution generated annually from architectural paint maintenance in the UK alone, current dust control tools such as vacuums remain too bulky, rigid, or disruptive to be used, making it undesirable and neglected by most paint workers.
