Continuous Glucose Monitor
This project explores the redesign of a transmitter for an implantable continuous glucose monitoring (CGM) system, developed in collaboration with BioTeq Ltd. The goal was to create a device that addresses the most common causes of CGM discontinuation — including discomfort, visible disease markers, and alarm fatigue — while offering improved integration into the user's lifestyle. Through a user-centered design approach, I led the process from problem definition and research to prototyping and testing. The final solution is a modular, discreet, and customizable transmitter that allows for greater freedom, control, and comfort in diabetes management. Key outcomes included: Customisable haptic alerts to prevent alarm fatigue Flexible attachment options (strap, adhesive) to reduce skin irritation Sleek, lifestyle-compatible aesthetics Quick charging, wireless connectivity, and waterproof casing This design not only enhances daily usability for individuals living with Type 1 and Type 2 diabetes but also aligns with BioTeq’s mission to innovate human implant technologies.

Problem
Despite the medical benefits of continuous glucose monitoring (CGM) systems, user dropout rates remain high — with up to 40% discontinuing use within the first year. The reasons are often not technical, but emotional and experiential: Skin irritation from adhesives Social stigma from visible medical devices Loud or intrusive alarms Incompatibility with active lifestyles These limitations contribute to alarm fatigue, anxiety, and loss of autonomy, making users feel more monitored than empowered. Existing designs prioritize function but overlook comfort, discretion, and the lived experience of diabetes management. This project set out to reimagine the transmitter — the most tangible component of the CGM system — as a wearable that seamlessly integrates into users’ daily lives without compromising clinical efficacy.
Solution
The result is a modular, discreet transmitter designed to work with implantable CGM sensors, offering users a more comfortable, customizable, and confidence-boosting experience. Key features include: Customisable haptic alerts that reduce alarm fatigue Flexible application options (strap or adhesive) to minimize skin irritation Low-profile, waterproof design that blends into daily life Wireless connectivity for seamless integration with smart devices By focusing on the user experience and emotional landscape of managing diabetes, this design transforms a clinical necessity into an intuitive, lifestyle-compatible tool — enabling users to take back control of their health with less friction and more confidence.

1. Research & User Insights The project began with an in-depth exploration of existing CGM systems and user behavior. Through interviews, persona development, and usability reviews, I identified the core challenges users face: discomfort, alarm fatigue, and visible medical aesthetics. These insights laid the foundation for user-centered design criteria that would inform the entire process.

2. Concept Development & Prototyping Based on the research, I generated a wide range of concepts through sketching, co-creation workshops, and design exploration. Three strong directions emerged—each addressing wearability, comfort, and modularity. I then iterated through physical prototypes, refining attachment systems, materials, and form based on user testing and mechanical evaluation.

3. Final Design & Implementation The outcome was a modular, discreet transmitter designed for daily comfort and emotional ease. Key features include customizable haptic feedback, a waterproof body, and multiple attachment methods. The final concept balances technical functionality with lifestyle integration, offering users a reliable and less intrusive way to manage diabetes.
