If your computer crashes, you can revive it by a reboot, an empirical solution that usually turns out to be effective. The rationale behind this solution is that transient faults, either in hardware or software,can be fixed by refreshing the machine state. Such a "silver bullet", however, could be futile in the future because the faults, especially those existing in the hardware such as Integrated Circuit(IC) chips, cannot be eliminated by refreshing. What we need is a more sophisticated mechanism to steer the system back to the right track. The "magic cure" is the Fault Tolerance On-Chip(FTOC) mechanism, which relies on a suite of built-in design-for-reliability logic, including fault detection, fault diagnosis, and error recovery, working in a self-supportive manner. We have exploited the FTOC to build a holistic solution ranging from on-chip fault detection to error recovery mechanisms to address faults caused by chips progressively aging. Besides fault detection, the FTOC paradigm provides attractive benefits, such as facilitating graceful performance degradation, mitigating the impact of verification blind spots, and improving the chip yield.

Plants possess many structural and functional properties that have a high potential to serve as concept generators for the production of biomimetic technical materials and structures. We present data on two features of plants (variable stiffness due to pressure changes in cellular structures and rapid self-repair functions) that may be used as models for biomimetic projects.

Resistive random access memory （RRAM） is one of the promising candidates for future universal memory. However, it suffers from serious error rate and endurance problems. Therefore, exploring a technical solution is greatly demanded to enhance endurance and reduce error rate. In this paper, we propose a reliable RRAM architecture that includes two reliability modules： error correction code （ECC） and self-repair modules. The ECC module is used to detect errors and decrease error rate. The self-repair module, which is proposed for the first time for RRAM, can get the information of error bits and repair wear-out cells by a repair voltage. Simulation results show that the proposed architecture can achieve lowest error rate and longest lifetime compared to previous reliable designs.

The existing self-repair methods,evolvable hardware and embryonic electronics( embryonics) are analyzed. Based on the advantages and disadvantages of the existing self-repair methods,a novel self-repair method named elimination-evolution self-repair method is proposed. The system can be repaired through elimination in real time and evolved to optimize the allocation of system resources with this method. The proposed self-repair method not only ensures the speed of the system's self-repair,but also makes full use of system resources to improve the system's self-repair capacity and provides a new self-repair approach for bio-inspired electronic system. In the end,the advantages of the proposed eliminationevolution self-repair method are verified through a simulation experiment.

A new self-repairing membrane for inflatable light weight structures such as rubber boats or Tensairity constructions is presented. Inspired by rapid self-sealing processes in plants, a thin soft cellular polyurethane foam coating is applied on the inside of a fabric substrate, which closes the fissure if the membrane is punctured with a spike. Experimental tests are carried out with a purpose built setup by measuring the air mass flow through a leak in a damaged membrane sample. It is shown that the weight per unit area of the self-repairing foam as well as the curing of the two component PU-foam under an overpressure influence the repair efficiency. Curing the foam under overpressure affects the relative density as well as the microstructure of the foam coatings. Maximal median repair efficiencies of 0.999 have been obtained with 0.16 *** 2 foam cured at 1 bar overpressure. These results suggest that the bio-inspired technique has the potential to extend the functional integrity of injured inflatable structures dramatically.
