We present a new method for spatiotemporal assignment and scheduling of energy harvesters on a medical shoe tasked with measuring gait diagnostics. While prior work exists on the application of dielectric elastomers (DEs) for energy scavenging on shoes, current literature does not address the issues of placement and timing of these harvesters, nor does it address integration into existing sensing...
Localized multisensory systems for medical diagnostics are becoming increasingly important due to the prevalence of lightweight sensors and new collection, storage, and communication platforms such as mobile phones and tablets. These systems are often comprised of multisensory arrays that can be inefficient in terms of energy and cost both in sensing and transmission. We make the following two key...
This paper presents an energy‐efficient and coverage‐preserving communication protocol which distributes a uniform energy load to the sensors in a wireless microsensor network. This protocol, called Distance‐based Segmentation (DBS), is a cluster‐based protocol that divides the entire network into equal‐area segments and applies different clustering policies to each segment to (1) reduce total energy...
Wearable sensing systems (WSS's) are emerging as an important class of distributed embedded systems in application domains ranging from medical to military. Such systems can be expensive and power hungry due to their multi sensor implementations that require constant use, yet by nature they demand low-cost and low-power implementations. Semantic multimodal compression (SMC) mitigates these metrics...
This paper introduces a new software development platform specifically designed for wireless health applications. Wireless health applications follow a unique paradigm encompassing body sensor networks. These networks are controlled by a central processing unit (such as a cell phone or PDA) that provides connectivity to health care professionals over a wide area network. With such architectures, health...
The improvement in processor performance through continuous breakthroughs in transistor technology has resulted in the proliferation of lightweight embedded systems. Advances in wireless technology and embedded systems have enabled remote healthcare and telemedicine. Continuous and real-time monitoring can discretely analyze how a patient's lifestyle affects his/her physiological conditions and if...
