Logical Functions

AbstractEmbedding mechanical logic into soft robotics, microelectromechanical systems (MEMS), and robotic materials can greatly improve their functional capacity. However, such logical functions are usually pre-programmed and can hardly be altered during in-life service, limiting their applications under varying working conditions. Here, we propose a reprogrammable mechanological metamaterial (ReMM). Logical computing is achieved by imposing sequential excitations. The system can be initialized and reprogrammed via selectively imposing and releasing the excitations. Realization of universal combinatorial logic and sequential logic (memory) is demonstrated experimentally and numerically. The fabrication scalability of the system is also discussed. We expect the ReMM can serve as a platform for constructing reusable and multifunctional mechanical systems with strong computation and information processing capability.

We summarize our recent work on a non-volatile logic building block required for energy-efficient information processing systems. A sequential logic device, in particular, an alternative non-volatile magnetic flip-flop has been introduced. Its properties are investigated and its extension to a very dense shift register is demonstrated. We show that the flip-flop structure inherently exhibits oscillations and discuss its spin torque nano-oscillator properties.

Microelectromechanical systems, or MEMS, constitute a group of microdevices that are just beginning to affect many areas of science and technology. In diverse fields including the automotive industry, aeronautics, cellular communications, chemistry, acoustics, and display technologies and other photonic systems, these highly functional devices are making a big name for themselves, despite their diminutive size.

Sunlight Energy

By growth in size and complexity (i.e., changing from more probable to less probable states), plants and animals appear to defy the second law of thermodynamics. The usual explanation describes the input of nutrient and sunlight energy into open thermodynamic systems. However, energy input alone does not address the ability to organize and create complex structures or explain life cycles – in particular, growth regulation and dying in the presence of adequate nutrients. Understanding the roles of macromolecules such as DNA, with their apparent information-processing capability, affords opportunity to understand biological order.

New Generation

In this talk, the development of key elements for BioPOEMS (Biomedical Polymer-based Opto Electro Mechanical Systems) will be discussed as a new generation of microscopic and microanalysis biochips. Current BioMEMS (Biomedical Microelectromechanical Systems) technology is in its infancy stage. Just as silicon-based microelectronics technology went through many stages since the late ‘60's, BioMEMS technology will have to overcome many obstacles before becoming a mature industry. The IC industry was made possible by the development of fabrication processes, integration technologies, and design tools. Similarly, the field of BioMEMS must prepare new components with biomaterials and tools for the development of new microsystems, enabling the combination of biological sensors and actuators with the rapidly growing capabilities of bioinformatics.Polymers are not only used in macroscopic systems, but are now increasingly finding use in the microscopic realm such as microfluidic devices. Among the many different classes of polymers, it is the fluoropolymers that provide the most unique material characteristics.

Simulation Results

Research on social networks has received remarkable attention, since many people use social networks to broadcast information and stay connected with their friends. However, due to the information overload in social networks, it becomes increasingly difficult for users to find useful information. This paper takes Facebook-like social networks into account, and models the process of information diffusion under information overload. The term view scope is introduced to model the user information-processing capability under information overload, and the average number of times a message appears in view scopes after it is generated is proposed to characterize the information diffusion efficiency. Through theoretical analysis, we find that factors such as network structure and view scope number have no impact on the information diffusion efficiency, which is a surprising result. To verify the results, we conduct simulations and provide the simulation results, which are consistent with the theoretical analysis results perfectly.
