Recent breakthroughs in wireless energy transfer-based rechargeable batteries enable a promising application of Wireless Charging Vehicles (WCVs) in Wireless Rechargeable Sensor Networks (WRSNs). This paper studies cooperative WCV schedules in WRSNs to optimize sensor recharging. The objective is to minimize the number of WCVs under the constraint that all sensors must be periodically recharged before...
The limited battery capacity of sensor nodes has become one of the most critical impediments that stunt the deployment of wireless sensor networks (WSNs). Recent breakthroughs in wireless energy transfer and rechargeable lithium batteries provide a promising alternative to power WSNs: mobile vehicles/robots carrying high volume batteries serve as mobile chargers to periodically deliver energy to sensor...
Urinary incontinence (UI) is one of the most acknowledged diseases that affected human health, and more than 1/5 females in this world suffer from this disease. In this paper, we present a novel electrical muscle simulator for the urinary incontinence, which adopted the wireless communication technique. The equipment is composed of a controller and an electrode pole. The electrode is inserted in female...
