A soft computing approach to localization in wireless sensor networks

Abstract: In this paper, we propose two intelligent localization schemes for wireless sensor networks (WSNs) The two schemes introduced in this paper exhibit range-free localization, which utilize the received signal strength (RSS) from the anchor nodes Soft computing plays a crucial role in both schemes In the first scheme, we consider the edge weight of each anchor node separately and combine them to compute the location of sensor nodes The edge weights are modeled by the fuzzy logic system (FLS) and optimized by the genetic algorithm (GA) In the second scheme, we consider the localization as a single problem and approximate the entire sensor location mapping from the anchor node signals by a neural network (NN) The simulation and experimental results demonstrate the effectiveness of the proposed schemes by comparing them with the previous methods

Transparent, stretchable, and rapid-response humidity sensor for body-attachable wearable electronics

Abstract: Stretchable and conformal humidity sensors that can be attached to the human body for continuously monitoring the humidity of the environment around the human body or the moisture level of the human skin can play an important role in electronic skin and personal healthcare applications. However, most stretchable humidity sensors are based on the geometric engineering of non-stretchable components and only a few detailed studies are available on stretchable humidity sensors under applied mechanical deformations. In this paper, we propose a transparent, stretchable humidity sensor with a simple fabrication process, having intrinsically stretchable components that provide high stretchability, sensitivity, and stability along with fast response and relaxation time. Composed of reduced graphene oxide-polyurethane composites and an elastomeric conductive electrode, this device exhibits impressive response and relaxation time as fast as 3.5 and 7 s, respectively. The responsivity and the response and relaxation time of the device in the presence of humidity remain almost unchanged under stretching up to a strain of 60% and after 10,000 stretching cycles at a 40% strain. Further, these stretchable humidity sensors can be easily and conformally attached to a finger for monitoring the humidity levels of the environment around the human body, wet objects, or human skin.
