Commercially available health monitors rely on rigid electronic housing coupled with aggressive adhesives and conductive gels, causing discomfort and inducing skin damage. Also, research‐level skin‐wearable devices, while excelling in some aspects, fall short as concept‐only presentations due to the fundamental challenges of active wireless communication and integration as a single device platform. Here, an all‐in‐one, wireless, stretchable hybrid electronics with key capabilities for real‐time physiological monitoring, automatic detection of signal abnormality via deep‐learning, and a long‐range wireless connectivity (up to 15 m) is introduced. The strategic integration of thin‐film electronic layers with hyperelastic elastomers allows the overall device to adhere and deform naturally with the human body while maintaining the functionalities of the on‐board electronics. The stretchable electrodes with optimized structures for intimate skin contact are capable of generating clinical‐grade electrocardiograms and accurate analysis of heart and respiratory rates while the motion sensor assesses physical activities. Implementation of convolutional neural networks for real‐time physiological classifications demonstrates the feasibility of multifaceted analysis with a high clinical relevance. Finally, in vivo demonstrations with animals and human subjects in various scenarios reveal the versatility of the device as both a health monitor and a viable research tool.

To reduce the cost of computing, Cloud computing has now one of the booming researching areas. Currently, the services that the Cloud computing is providing to its users are on demand over the internet, hence it is very persuading technology. As it stores data and the resources are distributed in the environment, so the security of the resources and data has become the major issue that is restricting the deployment of cloud computing environments. Various users are now using the cloud to store their data, such that the security of data storage is needed in this medium of storage. The basic objective of the cloud computing environment is providing security while storing the data on server of cloud. This paper is to review various techniques of security and issues from the aspect of both software and hardware for securing data in the cloud and targeted at improving the security of data and privacy preservation for the reliable environment of cloud. In this paper, it provides an approximate analytical research of the previous researches related to the security of data and techniques of privacy preservation that are used in cloud computing.
