Air Microfluidics-Enabled Active Compression Apparel

University of Waterloo Background
The air microfluidics-enabled active compression apparel belongs to the compression therapy market. The global compression therapy market size was valued at USD 3.1 billion in 2019 and is expected to reach USD 4.2 billion by 2025 at a compound annual growth rate (CAGR) of 4.8%. Compression therapy is the mainstay for treatment and management of chronic venous insufficiency (CVI), venous leg ulcers, chronic venous disease (CVD), deep vein thrombosis (DVT), lymphedema, dependent edema, varicose veins, venous thromboembolism (VTE), and gravitational eczema. This therapy is also preferred by sportspersons and athletes for treating musculoskeletal and spinal injuries and is routinely applied for the management of post orthopedic surgeries to alleviate pain, reduce swelling, and enable rapid functional recovery.
This market is driven by the significant growth in the aging and target patient populations, incidence of sports injuries and accidents, and clinical evidence favouring the adoption of compression therapy in the treatment and management of target diseases.
Technology Overview
Waterloo’s Air Microfluidics Enabled Active Compression Apparel provide a novel and disruptive microfluidic chip design which offers state-of-the-art sequential actuation capability with a miniaturized and low-cost control box (). The wearable control box makes the apparel/sleeve lightweight and portable with much lower cost, noise, and battery consumption than its competitive counterparts. Waterloo’s current prototype is an effective, affordable, and wearable active edema/lymphedema sleeve.
Current competitive technologies rely on solenoid valves (as many as 17) which are costly, heavy, noisy, and power hungry. This ultimately results in trade-offs between performance, cost, and portability for end-users.
Waterloo’s Air Microfluidic Enabled Active Compression Apparel addresses all of these issues by offering state-of-the-art performance, while being cost effective, easy to use (donning and doffing), portable and comfortable to wear.
Stage of development
Prototype developed and currently being validated.
