Understanding the composition of gases within our local environment and indoor spaces is crucial to both living a healthy lifestyle and leaving a positive impact on our planet for future generations. Today, we rely on the accurate measurement of gas sensors in many industries. For example, they warn our workforce of potentially harmful gases, can sense gas leaks in our homes, are able to identify out-of-date food produce, and even monitor our air-quality. In particular, poor air quality around major cities is currently a leading cause of death worldwide.Despite the vital role that gas sensors play in our current economy, high performance, reliable and inexpensive gas sensors are not available in the current market. This is due to the fact that specialised sensors are typically expensive whilst cheaper sensors tend to have major drawbacks. For example, many inexpensive commercial sensors today rely on materials called metal oxides, which are ideal materials for commercial applications due to their simple sensing circuitry and wide availability. However, in order for these materials to detect gases, they typically have to be heated to temperatures above 250°C, which drastically limits the scope of their applications. For example, they cannot be deployed near potentially flammable gases, integrated into wearable technologies or used in low-power scenarios.Anaphite are a team of expert scientists and engineers who are committed to producing new materials that have a substantial impact on our green future. We have developed a novel process which substantially modifies CSOA gas sensing materials. Preliminary results have shown that we are able to create materials hundreds or thousands of times more sensitive than CSOA technologies, all while operating at much lower power. Crucially, these materials have been found to work at room temperatures, which could transform the current gas sensing market and enabling applications not seen before.We propose an industrial research project whereby our team work with advanced machine learning experts to deliver products able to accurately sense a broad range of gases for widespread applications. We believe that the integration of our technology along with the computer processing strategies currently available could create products unmatched in performance at a cost which is affordable to everyone.

了解当地环境和室内空间中的气体成分对于健康的生活方式和为子孙后代留下积极的影响至关重要，例如，我们在许多行业中都依赖于气体传感器的精确测量。它们可以警告我们的员工潜在的有害气体，可以感知我们家中的煤气泄漏，能够识别过期的食品，甚至可以监测我们的空气质量。特别是，目前主要城市周围的空气质量较差。世界范围内的死亡原因。尽管气体传感器发挥着至关重要的作用在我们当前的经济中，高性能、可靠且廉价的气体传感器在当前市场上尚不可用，这是因为专用传感器通常很昂贵，而便宜的传感器往往具有主要缺点，例如许多廉价的商用传感器。如今依赖于称为金属氧化物的材料，由于其简单的传感电路和广泛的可用性，这些材料是商业应用的理想材料，但是，为了使这些材料能够检测气体，通常必须将它们加热到 250°C 以上的温度。激进限制了它们的应用范围。例如，它们不能部署在潜在易燃气体附近、集成到可穿戴技术中或用于低功耗场景。Anaphite 是一个由专家科学家和工程师组成的团队，致力于生产对我们的绿色未来产生重大影响的新材料。已经开发出一种新颖的工艺，可大幅改进 CSOA 气体传感材料。初步结果表明，我们能够制造出比 CSOA 技术灵敏数百倍或数千倍的材料，而且这些材料的工作功率要低得多。去工作在室温下，这可能会改变当前的气体传感市场并实现以前从未见过的应用。我们提出了一个工业研究项目，我们的团队与先进的机器学习专家合作，提供能够准确感应各种气体的产品，以实现广泛的应用。我们相信，我们的技术与当前可用的计算机处理策略的集成可以以每个人都能负担得起的成本创造出性能无与伦比的产品。
