Lin LIU, Jing LIU

《机械工程前沿（英文）》 2011年第6卷第2期页码 160-175 doi: 10.1007/s11465-011-0216-0

摘要：

Biomedical sensors have been widely used in various areas of biomedical practices, which play an important role in disease detection, diagnosis, monitoring, treatment, health management, and so on. However, most of them and their related platforms are generally not easily accessible or just too expensive or complicated to be kept at home. As an alternative, new technologies enabled from the mobile phones are gradually changing such situations. As can be freely available to almost everyone, mobile phone offers a unique way to improve the conventional medical care through combining with various biomedical sensors. Moreover, the established systems will be both convenient and low cost. In this paper, we present an overview on the state-of-art biomedical sensors, giving a brief introduction of the fundamental principles and showing several new examples or concepts in the area. The focus was particularly put on interpreting the technical strategies to innovate the biomedical sensor technologies based on the platform of mobile phones. Some challenging issues, including feasibility, usability, security, and effectiveness, were discussed. With the help of electrical and mechanical technologies, it is expected that a full combination between the biomedical sensors and mobile phones will bring a bright future for the coming pervasive medical care.

electricity shortage through human power: Technical opportunities from direct or indirect utilizations of the pervasive

Dan DAI, Jing LIU

《能源前沿（英文）》 2012年第6卷第3期页码 210-226 doi: 10.1007/s11708-012-0200-3

摘要： With the energy and environmental problems becoming increasingly serious, human power, as a pervasive, renewable, mobile and environment friendly energy, draws more and more attention over the world. In this paper, the most basic features of human power are presented. The currently available human power harvesting theories and devices are briefly reviewed and compared. Further, direct or indirect utilization of human power in daily life, especially transportation and home appliances, such as human-powered car, watercraft, aircraft, washing machine and television etc. are summarized. Considering that the total energy from an individual is rather limited, as previously focused by most of the former works, it is conceived in this paper that an important future for large scale use of human powers lies in the efficient conversion, collection and storage of such energy from discrete people and then use it later on as desired. With the huge amount of energy gathered, the application category of human power would be significantly expended. Starting from this point, three technical ways towards efficiently utilizing human power are sketched, which are termed as human-powered grid (HPG), human-powered charger (HPC) and human-powered storage (HPS), among which, HPG is capable of collecting the electric power produced by each individual at different regions and thus can supply unique and flexible power to the customers covered in the area, without relying on the conventional electricity grid. The HPC can then charge various kinds of electrical devices instantly by a human driven generator which converts human power into electricity. Finally, the HPS can store electricity in time for later use. In this way, even for the devices requiring electricity that is strong enough, the collected human power can also serve as its reliable energy source. Meanwhile, utilization of human power becomes rather convenient and timely which guarantees its practical value. It is expected that with further research and increasing applications, human power could partially relieve the current global electricity shortage and environmental issues via its pervasive contribution.

Hip-mounted electromagnetic generator to harvest energy from human motion

Dan DAI,Jing LIU

《能源前沿（英文）》 2014年第8卷第2期页码 173-181 doi: 10.1007/s11708-014-0301-2

摘要： A type of electromagnetic hip-mounted generator (EHG) is proposed to harvest energy from human hip motion to generate electricity. Based on the law of electromagnetic induction, the EHG generator can convert the kinetic power of the thigh swing into electrical energy during walking or running. To demonstrate the feasibility of the present method, a prototype of the EHG has been designed and fabricated. A theoretical analysis has been conducted to interpret the working behavior of this prototype. In addition, the performance of the system has been experimentally tested through a rotary motor and human body motion. When driven by the rotary motor at a rotation speed of 100 r/min, the open-circuit voltage of this prototype is 2.5 V. Further, a maximum open-circuit voltage of approximately 1 V and a maximum output power of 284 μW could be produced respectively when walking with an EHG at a speed of 1.47 m/s. This handy renewable energy technology is promising as a pervasive electricity generation system for a group of wearable or implanted sensors, actuators and mobile electronics.

从资源共享到服务共享：透明计算的机遇与挑战

张尧学,周悦芝

《中国工程科学》 2009年第11卷第8期页码 10-17

摘要：

随着计算机和网络技术以及应用的不断快速发展，计算模式从最初的以主机计算为主，发展到以桌面(PC)计算为主，再发展到现在的以网络计算为主，乃至普适计算。然而，迄今为止的计算模式还是遵循以单机或单机联合为基础的单机思维模式，因此，目前的计算模式还是一种以“资源共享”为主要特征的计算。在网络和普适计算的新时代，用户关心的主要是服务和服务共享，计算机也将从以“资源共享”为特征的计算过渡到以“服务共享”为特征的计算。笔者提出一种适应于“服务共享”的计算模式——透明计算，并对其概念、体系结构及相关关键技术进行介绍。此外，还对透明计算的未来发展及影响进行展望。

BORON：面向普适计算的超轻量低功耗加密设计 Article

Gaurav BANSOD,Narayan PISHAROTY,Abhijit PATIL

《信息与电子工程前沿（英文）》 2017年第18卷第3期页码 317-331 doi: 10.1631/FITEE.1500415

摘要：我们提出一种超轻量，紧凑且低功耗的分组密码：BORON。BORON是一种替换、互换网络，运行于64位纯文本上，支持128位或80位密钥长度。针对128位密钥和80位密钥，BORON的紧凑结构分别需要1939个和1626个等效门（gate equivalents, GE）。BORON包含移位、循环移位和异或操作。其的独特设计有助于在较少的回合内产生大量的活动S-box，从而挫败针对加密的线性或差分攻击。BORON在硬、软件平台上均具有较好的性能。与轻量加密LED相比，BORON具有更低的功耗水平；与现有SP网络加密相比，BORON具有更高的吞吐量。本文还展示了BORON的安全性分析及其作为超轻量紧凑型加密的性能。BORON可适用于将引脚面积和功率耗散作为关键参数的应用。
