DESCRIPTION (provided by applicant): 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. 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（由申请人提供）：人类越来越依赖于技术，特别是电子设备。在过去的十年中，电子设备已经变得更加移动的，使得人们能够在城市或荒野中移动时使用医疗设备、蜂窝/卫星电话、膝上型计算机和GPS。目前，所有这些设备都使用寿命有限的电池，并给设备增加了相当大的重量。电池有限的寿命和巨大的重量对于救灾工作者、第一反应者、野外科学家和长期探险的探险家来说尤其重要。这些人通常必须携带沉重的包（> 80磅），大部分重量是更换电池。数百万美元已投入开发便携式和可再生的人类产生的能源，但一直没有解决方案。为了解决这个问题，我们开发了一种被动设备，即悬挂式背包，它在行走过程中提取机械能，然后将其转化为电能。当携带80磅的负载时，个人可以产生超过7 W的电力，并且在40磅的负载下可以产生大约2 W的电力。这是一个重要的，因为以前发表的尝试与设备安装在鞋产生约300倍（约20 W）。我们的背包产生的电力可以实时为设备供电，并为电池充电。有趣的是，代谢实验表明，产生这种电力只会使代谢率增加2- 3%，实际上会降低携带负荷的能量成本。此外，由于减少了身体上的力，使用悬挂式背包携带负载在人体工程学上比标准背包更舒适，因此应该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，发电背包具有巨大的商业价值。为了将“概念证明”商业化，需要更多的创新设计/工程。 具体目标1：减轻悬吊式发电背包的重量。 具体目标2：制作发电背包的数学/计算模型。 具体目标3：开发电路来控制阻尼，功率便携式设备和电荷存储设备。 在发展中国家，该设备也有同样引人注目的健康/社会应用。世界上很大一部分人口靠电网生活。正因为如此，他们的饮用水经常被病原体污染，他们没有常规的医疗检测，也没有获得疫苗的机会。已经开发了许多便携式低功率设备，这些设备可以提供很大的改进，但是缺少的是小的电力来源。背包可以提供足够的电力：用便携式紫外线灯（SteriPen）消毒水，帮助提供必要的疫苗冷藏，简单的诊断测试和紧急情况下的通信设备。在第二阶段，将开发一种新的，更轻，更有效的原型并进行临床测试，利用第一阶段开发的改进技术和理解。我们的发电背包提供的电力独立性对于救灾人员、森林消防队员、野外科学家、探险家、环境测试人员和一些急救人员来说非常重要，他们都必须在电网之外工作。在发展中国家也有同样引人注目的健康应用。世界上有很大一部分人口一生都生活在电网之外：因此，他们的饮用水经常被病原体污染，他们没有常规的医学检测，也无法获得必须冷藏的疫苗和药物。许多便携式，低功耗的设备已经开发出来，背包可以提供缺少的小电源：消毒水（UV; SteriPen），帮助接种疫苗，简单的诊断测试和紧急情况下的通信。
