A linear actuator is provided, comprising a housing defining an interior channel, a stop extending from the housing and displaceable relative to the housing, and at least one wire formed of a shape-memory alloy, the wire being attached at a first end to the stop and at a second end to the housing. When heated to a predetermined temperature, the wire applies a pulling force to the stop to cause the stop to slide in a first direction into the housing interior channel. A spring located in the housing interior channel applies a biasing force to the stop in a …

Wireless sensor and actuator networks have expanding applications which requires better throughput, power efficiency and cost effectiveness. This study intends to contribute to the growing pool of knowledge on WSAN especially in the design for novel applications such as image or video over WSANs, and solar energy and RF energy harvesting for the WSAN nodes. Two basic scalable wireless sensor and actuator networks were implemented and characterized in terms of throughput and power consumption. The two WSANs are the Zigbee-based WSAN which is based on the IEEE 802.15.4 protocol, and the ISM-based Zigbee which makes use of the industrial, scientific …
