A light-weight, portable miniaturized oxygen concentrator that can produce 90+ %O2 has been designed by the research team. This technology is one of the first to demonstrate air separation using a light-weight compact bench-scale unite capable of continuously producing 1-3 SLPM of 90+% O2. The design of single column rapid pressure swing adsorption process integrated with a product storage tank requires minimum instrumentation and the adsorbent inventory is less than one third that of commercially available medical oxygen concentrators (MOC) in the market. In this project, a prototype unit based on the patented novel design concept will be built using miniaturized valves, flow and pressure sensors. A micro-processor based control algorithm will be developed for the operation of the cyclic adsorption process. Furthermore, the weight of the unit will be optimized using aluminum or plastic based material for the design and construction of the adsorption column. Miniaturization of a MOC design is a highly sought-after goal. A more compact MOC design will benefit millions of people who suffer from chronic obstructive pulmonary disorder (COPD) and require home oxygen therapy. A portable MOC unit will provide greater mobility to these patients for exercise and improved cardiovascular health. A new 'Snap On' design of a miniaturized MOC system which can be used in conjunction with an existing compressed air source as in a hospital room or an industrial site can further extend the application of this product by eliminating the need of a dedicated air compressor. Other potential applications of this technology may be on-board oxygen supply in airlines and cruise ships, military camps, etc.

研究小组设计了一种重量轻、便携式小型制氧机，可以生产90+ %O2。该技术是第一个使用能够连续生产1-3 SLPM的90+% O2的轻质紧凑型实验室规模单元演示空气分离的技术之一。与产品储罐集成的单柱快速变压吸附工艺的设计需要最少的仪器，并且吸附剂存量小于市场上市售医用氧气浓缩器（MOC）的三分之一。 在该项目中，将使用小型化阀门、流量和压力传感器构建基于专利新颖设计概念的原型装置。一个基于微处理机的控制算法将被开发用于循环吸附过程的操作。此外，将使用铝或塑料基材料来优化单元的重量以用于吸附柱的设计和构造。MOC设计的小型化是一个非常受欢迎的目标。更紧凑的MOC设计将使数百万患有慢性阻塞性肺疾病（COPD）并需要家庭氧气治疗的人受益。便携式MOC单元将为这些患者提供更大的移动性，以进行锻炼并改善心血管健康。微型MOC系统的新型“卡扣式”设计可与医院病房或工业现场中的现有压缩空气源结合使用，通过消除对专用空气压缩机的需求，可以进一步扩展该产品的应用。该技术的其他潜在应用可能是航空公司和游轮、军营等的机载氧气供应。
