Periodic arrays of shunted piezoelectric patches are employed to control the propagation of elastic waves in phononic beams. Each piezo-patch is connected to a single resistance-inductance-negative ...

By using piezoelectric actuators coupled to the tool-holder, one can choose to use different passive and active controls, generating a more versatile tool to control machining vibration. However, one ...

'Electron shower' technique unlocks advanced piezoelectric films for next-generation electronics. by Anna Ettlin, Swiss Federal Laboratories for Materials Science and Technology ...

A project on gait analysis and recognition using accelerometer sensor data and computational techniques to recognize individuals based on their unique walking patterns. julia-language data-analysis ...

Abstract: Wireless motion and large capacity are two important characteristics for practical applications of the miniature robots, and become more challenging as the decrease of the robot size. Here, ...

Investigation results obtained indicate that both types of membranes are composed of thin fibers: (0.57 ± 0.25) μm for PTFE membranes and (0.43 ± 0.14) μm for VDF-TeFE membranes. Moreover, the fibers ...

For piezoelectric applications, metals are commonly used, often with the addition of nitrogen to produce nitrides such as aluminum nitride.

Objectives To examine the joint associations of accelerometer-measured physical activity and sedentary time with all-cause mortality. Methods We conducted a harmonised meta-analysis including nine ...

Objective Self-reports of physical activity (PA) have been the mainstay of measurement in most non-communicable disease (NCD) surveillance systems. To these, other measures are added to summate to a ...
