Piezoelectric acceleration sensor and piezoelectric acceleration sensor device
The Journal of the Acoustical Society of America, 1993ABSTRACT The invention relates to a piezoelectric acceleration sensor and to a piezoelectric acceleration device which use a film piezoelectric element. Specifically, the piezoelectric acceleration sensor and the piezoelectric acceleration sensor device generate relatively large outputs when acceleration occurs along the sensing axis, but ...

Respiratory monitoring with an acceleration sensor
Physics in Medicine and Biology, 2011Respiratory gating radiotherapy is used to irradiate a local area and to reduce normal tissue toxicity. There are certain methods for the detection of tumor motions, for example, using internal markers or an external respiration signal. However, because some of these respiratory monitoring systems require special or expensive equipment, respiratory ...

Accelerating Initialization for Sensor Networks
GLOBECOM 2009 - 2009 IEEE Global Telecommunications Conference, 2009Initialization is an indispensable process for wireless sensor networks since newly deployed sensors lack a reliable infrastructure for communication. Many efforts have been made to address the problem on initialization. However, most of them fall into the category of energy efficiency.
