The miniaturization of electronic devices enabled the development of modern information technologies. The concept of miniaturization has also been applied to mechanical and fluidic components to develop the versatile technologies of Micro Electro Mechanical Systems (MEMS) and Microfluidics. MEMS can be generally defined as systems of miniaturized electro-mechanical sensors and actuators (e.g. air bag sensors), while Microfluidics deals with fluid handling in geometries below a millimetre. Especially in the area of Microfluidics, the reduction in size and integration of multiple functions has produced structures with capabilities that far exceed those of conventional systems and also have the potential of being mass produced at a low cost. Microfluidic technologies include the so-called Point-of-Care Testing, which provides a means for healthcare diagnostics at the site of the patient. That is, diagnostics that previously required several steps, highly skilled personnel and expensive equipment can be replaced with microfluidic methods that generate easy access to regular testing in real-time that can be carried out in privacy at home. Likewise, the microfluidic Lab-on-a-Chip technology aims to integrate a multitude of laboratory functions on a microchip of only a few square centimetres in size. A typical application could be the monitoring of pathogens in drinking water right at the source. However, the supply of electrical power to these devices continues to impose a barrier since the development of power source miniaturization has not kept the pace. The majority of microfluidic devices are still powered by external and oversized power supplies, leading to several problems which compromise the advantages of miniaturization. An attractive approach to power micro devices seems to be the use of embedded power sources within the device. In this research, we propose the development and optimization of a rechargeable, integrated microbattery based on the nickel/metal hydride electrochemistry. Consequently, this approach requires that the microbattery is manufactured with the state of the art microfabrication techniques onto substrates which are commonly used for microfluidic devices such as glass. This research program will ultimately establish a new class of integrated power sources for a variety of applications, which will potentially have a tremendous impact on the broad field of MEMS and Microfluidic devices. The further development of such systems for portable medical diagnostics and environmental monitoring will directly benefit the Canadian healthcare system by providing affordable and easy access to regular testing wherever it is required. Also, the research program will prove a unique multidisciplinary training environment and assist in the expansion of `high tech' jobs in Canada through the training of highly qualified engineers/scientists.**

电子设备的微型化使现代信息技术的开发。微型化的概念也已应用于机械和流体成分，以开发微电机械系统（MEM）和微流体的多功能技术。 MEMS通常可以定义为微型机电传感器和执行器（例如气囊传感器）的系统，而微流体学则处理在毫米以下的几何形状的流体处理。尤其是在微流体学领域，大小的降低和多个功能的整合产生了具有远远超过常规系统的能力的结构，并且具有低成本产生的质量的潜力。微流体技术包括所谓的护理点测试，该测试为患者部位提供了医疗诊断的手段。也就是说，以前需要几个步骤的诊断，可以用微流体方法代替高技能的人员和昂贵的设备，这些方法可以实时实时访问常规测试，可以在家中进行隐私。同样，微流体实验室芯片技术旨在在仅几秒钟的微芯片上整合众多实验室功能。典型的应用可能是对源饮用水中病原体的监测。但是，由于电源微型化的发展并没有保持步伐，因此向这些设备的电力供应继续施加障碍。大多数微流体设备仍由外部和超大电源提供动力，导致了一些损害小型化优势的问题。一种有吸引力的微型设备的方法似乎是设备中嵌入式功率来源的使用。在这项研究中，我们提出了基于镍/金属氢化物电化学的可充电，集成微生物的开发和优化。因此，这种方法要求微生物是用最先进的微加工技术制造的，这些技术通常用于微流体设备（例如玻璃）。该研究计划最终将为各种应用建立新的集成电源，这可能会对MEMS和微流体设备的广泛领域产生巨大影响。用于便携式医疗诊断和环境监测系统的此类系统的进一步开发将直接通过在需要的任何地方提供可负担得起且易于访问常规测试的加拿大医疗保健系统。此外，该研究计划将证明一个独特的多学科培训环境，并通过培训高素质的工程师/科学家来帮助扩大加拿大的“高科技”工作。**
