DESCRIPTION (provided by applicant): Project Summary/Abstract: Humans have become increasingly dependent on technology, particularly electronic devices. In the past decade, electronic devices have become more mobile, enabling people to use medical devices, cellular/satellite phones, laptop computers, and GPS as they move around cities or in the wilderness. At present, all of these devices run off of batteries which have limited lifetimes and add considerable weight to the device. The combination of limited lifetimes and large weight of batteries is particularly crucial to disaster relief workers, first responders, field scientists and explorers on prolonged expeditions. These individuals often must carry heavy packs (> 80 lbs), and much of the weight is replacement batteries. Millions of dollars have gone into developing a portable and renewable human-generated energy source but there has not been a solution. To solve this problem, we developed a passive device, the Suspended-load Backpack, which extracts mechanical energy during walking and then converts it to electricity. While carrying an 80 lb load, individuals can generate in excess of 7 W of electricity, and approximately 2 W with a 40 lb load. This is a significant because previously published attempts with devices fitted in shoes generated ~300-fold less (~20 W). The electricity generated by our backpack can be used to power equipment in real-time, and recharge batteries. Interestingly, metabolic experiments show that generating this electricity increases the metabolic rate by only 2-3%, and actually reduces the energetic cost for carrying a load. Further, carrying the load is ergonomically more comfortable with the Suspended-load Backpack than standard ones because of reduction in forces on the body, and thus should reduce common orthopedic injury. As backpacks represent a $295 million annual business, an electricity-generating backpack has substantial commercial value. Additional innovative design/engineering is necessary to bring the "proof of concept" to commercialization. SPECIFIC AIM 1: Reduce the weight of the Suspended-load electricity-generating backpack. SPECIFIC AIM 2: Make a mathematical/computational model of the electricity-generating backpack. SPECIFIC AIM 3: Develop circuitry to control damping, power portable devices and charge storage devices. There are equally compelling health/societal applications for the device in Developing Countries. A large percentage of the world's population lives off the electrical grid. Because of this, their drinking water is often contaminated with pathogens, they have no routine medical testing, nor access to vaccines. Many portable, low power devices have been developed which can provide a great improvement but what is missing is a small source of electricity. The backpack can provide sufficient power for: sterilizing water with portable UV lamps (SteriPen), help provide requisite refrigeration of vaccines, simple diagnostic tests, and communication devices in the case of emergencies. In Phase II, a new, lighter and more efficient prototype will be developed and clinically tested, taking advantage of the improved technologies and understanding developed in Phase I. Project Narrative: Electricity independence provided by our electricity-generating backpack is extremely important to disaster relief workers, forest fire fighters, field-scientists, explorers, environmental testers, and some first responders, all of whom who must function off the electric-grid. There are equally compelling health applications in Developing Countries. A large portion of the world population lives their whole lives off the electrical-grid: Hence, their drinking water is often contaminated with pathogens, they have no routine medical testing, nor access to vaccines and medicines that must be refrigerated. Many portable, low power devices have been developed, and the backpack can provide the missing small source of electricity for: sterilizing water (UV; SteriPen), helping refrigerate vaccines, simple diagnostic tests, and communications in the case of emergencies.

描述（申请人提供）：项目摘要/摘要：人类已经越来越依赖技术，尤其是电子设备。在过去的十年中，电子设备已变得更加流动，使人们能够在城市或荒野中移动时使用医疗设备，手机/卫星电话，笔记本电脑和GP。目前，所有这些设备都由寿命有限的电池播放，并为设备增加了相当大的重量。有限的寿命和大量电池的结合对于救灾工人，急救人员，现场科学家和探险家在长时间的探险中尤为重要。这些人通常必须携带重包（> 80磅），而大部分重量是替换电池。数百万美元用于开发一种便携式和可再生的人类生成的能源，但没有解决方案。为了解决这个问题，我们开发了一个被动装置，即悬挂式负载背包，该设备在步行过程中提取机械能，然后将其转换为电力。在承载80磅的负载时，个人可以产生超过7 W的电力，而40磅的负载约为2 W。这很重要，因为以前使用安装在鞋子中的设备的尝试少了约300倍（约20 w）。我们的背包产生的电力可用于实时电力设备，并充电电池。有趣的是，代谢实验表明，产生这种电力只会使代谢率仅增加2-3％，并且实际上降低了承载负载的能量成本。此外，由于降低了体内的力，承载负载在人体工程学上比悬挂装载背包更舒适，因此应减少常见的骨科损伤。由于背包代表了2.95亿美元的年度业务，因此发电的背包具有可观的商业价值。为了将“概念验证”带入商业化是必要的其他创新设计/工程。具体目标1：减少悬挂式负载产生的背包的重量。特定目标2：制作产生电力背包的数学/计算模型。特定目标3：开发电路以控制阻尼，便携式设备和充电存储设备。在发展中国家，该设备具有同样令人信服的健康/社会应用。世界上很大一部分人口都生活在电网上。因此，他们的饮用水经常被病原体污染，他们没有常规的医疗测试，也没有接种疫苗。已经开发了许多便携式，低电源设备，可以提供很大的改进，但缺少的是少量电力来源。背包可以为：使用便携式紫外线灯（Steripen）对水进行灭菌，有助于提供疫苗的必要冷藏，简单的诊断测试和通信设备在紧急情况下。在第二阶段中，将开发和临床测试的新的，更轻松，更有效的原型，利用在第一阶段的技术和理解。项目叙述性：我们的电力产生背包提供的电力独立性对救灾工人来说非常重要，对灾害工人，森林消防员，现场科学家，探险家，探险家，环境测试者以及所有急救人员，以及所有首次驱动器，以及所有驾驶员，以及某些驾驶员，以及所有驾驶员，以及某些驾驶员，以及所有驾驶员，以及某些驾驶员，以及某些驾驶员。发展中国家也有同样令人信服的健康应用。世界上很大一部分人口都活在电网上：因此，他们的饮用水经常被病原体污染，没有常规的医学测试，也没有使用必须冷藏的疫苗和药物。已经开发了许多便携式，低电源设备，背包可以为：消毒水（紫外线; steripen）提供缺失的电力来源，在紧急情况下帮助冷藏疫苗，简单的诊断测试和通信。
