Smart diaper moisture detection system described is a paper-based disposable moisture-activated RFID system that could be incorporated into the traditional cellulose-based diaper. The tag is semi-passive in the sense that it has no internal battery but incorporates a built-in energy conversion sensor (Action-Activated Tag). The tag with sensor unit is optimized for low-cost manufacturing, utilizes screen-printing with electrically conductive ink on paper-based substrates and inherits very low EM radiation. A discussion on the manufacturability and cost efficiency of the system is presented. A prototype system is shown and other possible application areas of the system are mentioned.

    • "Majority of the existing commercial products [3] [4] are targeted at children for self toilet training and operate in standalone unit only. Though there are some active research projects [5] [6] on enuresis sensors for wetness detection, there is limited work done for dementia elderly with incontinence problems, either to alleviate patients' or caregivers' problems, or to mitigate the problem through controlled voiding in term of a holistic continence management system.

    ABSTRACT: Elderly patients, especially those with dementia may suffer incontinence and related problems due to decline in physical and mental abilities. This paper presents the design, development and deployment of a smart wireless continence management system in a nursing home which addresses the pressing need for reliable continence assessment to alleviate the inconveniences faced by the elderly and caregivers. Preliminary results are promising for long-term incontinence care.

    ABSTRACT: Placing fire detectors in a forest is usually associated with powering problems since the sensors do not have access to external power supply and a periodical change of internal batteries is an undesired option. This paper presents an approach where the fire sensor itself, when heated by nearby fire, generates electrical energy to power a radio transmitter. Presented energizing fire sensor is environmentally friendly and can be mass produced at a very low cost. Upon activation the sensor produces enough power necessary to operate most standard radio transmitters depending on what communication system is chosen for operation. The fire detector unit can be deployed from either helicopter or manually from the ground. The sensor can be designed to activate itself at different temperatures to suit different climate zones. Rough guidelines are given for estimation of attenuation of radio wave propagation in forest areas in order to predict maximum transmit distance.
