Advanced Materials Technologies, EarlyView.This study presents a braided fiber‐reinforced sleeve that amplifies strain in soft materials, enhancing their performance in stretchable devices like sensors and energy harvesters. By reinforcing and elongating encased materials, the sleeve increases the “effective” strain.

A Bistable Assistive Device for Wireless Control of a Dysfunctional Bladder Under Minimal Stress
Advanced Materials Technologies, EarlyView.This paper presents a wireless system designed to restore bladder function in patients with an underactive bladder (UAB). The system features a multilayered structure, combining a pre‐shaped restoration layer with a spring‐based actuator. The system delivers 95–100% voiding efficiency within a 10‐s activation while ensuring minimal stress on the ...

Cryptographic obfuscation for smart contracts: Trustless bitcoin bridge and more
Blockchain: Research and Applications, 2023 Privacy protection for smart contracts is currently inadequate. Existing solutions for privacy-preserving smart contracts either support only a limited class of smart contracts or rely on noncryptographic assumptions.We propose a cryptographic ...

Mutation Testing for Ethereum Smart Contract [PDF]
arXiv, 2019 Smart contract is a special program that manages digital assets on blockchain. It is difficult to recover the loss if users make transactions through buggy smart contracts, which cannot be directly fixed. Hence, it is important to ensure the correctness of smart contracts before deploying them.

Transactional Smart Contracts in Blockchain Systems [PDF]
arXiv, 2019 This paper presents TXSC, a framework that provides smart contract developers with transaction primitives. These primitives allow developers to write smart contracts without the need to reason about the anomalies that can arise due to concurrent smart contract function executions.

Poka: A Necro‐Robot Beetle with a Measured Payload Ratio of 6847%
Advanced Robotics Research, EarlyView.Here, Poka, a necro‐robot beetle with the ability to carry more than 68 times its own weight, is introduced, making it also a walking robot with the highest payload ratio measured to date. This paper is concerned with the design, manufacture and validation of ‘Poka', a novel millimetre‐scale necro‐robot aimed at bridging the performance gap between ...
