Shape memory alloy (SMA) has great potential to develop light and compact artificial muscle (AM) due to its muscle-like high power-to-weight ratio, flexibility and silent operation properties. In this paper, SMA self-sensing properties are explored and modeled in depth to imitate the integrated muscle-like functions of actuating and self-sensing for SMA-AM based on the investigation of SMA elec...

Spool position feedback in an electrohydraulic valve typically requires a spool displacement sensing device such as a LVDT. Self-sensing is the methodology to obtain spool displacement information directly from the solenoid spool actuators, thus obviating the additional cost and footprint of a LVDT or another displacement sensing device. A self-sensing scheme that uses only the measurement of e...

Participatory sensing services utilizing the abundant social participants with sensor-enabled handheld smart device resources are gaining high interest nowadays. One of the challenges faced is the recruitment of participants by fully utilizing their daily activity behavior with self-adaptiveness toward the realistic application scenarios. In the paper, we propose a self-adaptive behavior-aware ...

This chapter aims to develop a self-sensing technique to measure the displacement and the force in piezoelectric microactuators dedicated to micromanipulation and microassembly contexts. In order to answer the requirements in these contexts, the developed self-sensing should perform a long duration measurement of constant signals (displacement and force) as well as a high precision. Furthermore...

in previous papers authors have considered agents as inertia-less self driven particles and designed a flocking algorithm. application of this algorithm to agents with considerable inertial characteristics needs a behavioural controller. the controller uses the local information and helps every agent to imitate the desired behaviour as a member of the flocking frame which covers the main issue ...

Wireless sensor networks represent a new paradigm shift in ad hoc networks. In addition to ad hoc deployment and wireless communication capabilities, sensor nodes use on-board sensing and processing to sense (or detect) application specified events of interest. An ad hoc network of randomly deployed wireless sensor nodes is formed by having nodes pursue neighbor discovery and subsequent self or...
