This Small Business Innovation Research Phase I research project involves using olfactory neuron cells integrated with electronic circuits, and interfacing with a wireless hardware based on ZigBee technology for detection at a standoff distance. Recent experiments with pouched rats have demonstrated that their highly sensitive olfactory system can detect and recognize vapors diffusing from IEDs. The vapor molecules of the explosive bind to specialized receptors on the cilia of olfactory neuron cells in the nose, triggering an electrical response that propagates to the brain. This approach takes advantage of the sensitivity and specificity of olfactory sensory neurons, which are unequaled by any state-of-the-art human-made sensor technologies. High-sensitivity front-end amplifier circuits, fabricated on the same silicon die, are able to detect action potentials and amplify the electrical signals toward subsequent transmission through a ZigBee wireless system. There is urgent need on the part of the U.S. military to develop effective IED detection systems since IEDs account for the majority of U.S. casualties in Iraq. By modest alterations, the same technology can be used in the transportation of sensitive goods such as medicine and weapons as well as security and protection of sensitive assets. Monitoring and protecting working and living environments against harmful pathogens is another market.

这项小型企业创新研究阶段研究项目涉及使用与电子电路集成的嗅觉神经元细胞，并与基于Zigbee技术的无线硬件接口在漫不经心的距离处检测。袋中大鼠的最新实验表明，它们的高度敏感的嗅觉系统可以检测并识别从IED扩散的蒸气。爆炸物的蒸气分子与鼻子中嗅觉神经元细胞纤毛的专用受体结合，引发了传播到大脑的电反应。这种方法利用了嗅觉感觉神经元的敏感性和特异性，这些感觉神经元被任何最新的人制造的传感器技术无与伦比。高敏性前端放大器电路（在同一硅模具上制造）能够检测动作电位并通过Zigbee无线系统扩大电信号向随后的传输。由于IED占伊拉克的大多数伤亡人数，因此美国军方迫切需要开发有效的IED检测系统。通过适度的改变，可以将相同的技术用于运输敏感商品，例如医学和武器以及对敏感资产的安全和保护。监测和保护工作和生活环境免受有害病原体的影响是另一个市场。
