Analysis on the contents of Macao elderly care service policy.

The global trend of an increasingly ageing society poses significant healthcare and socio-economic challenges for policymakers and caregivers. As Macao, China, entered an ageing society, policymakers were deeply concerned about this issue, then they launched a ten-year action plan in 2016 to improve healthcare services and increase geriatric education, which made great progress. This research aims to investigate the impact of these policy tools on elderly care services by using the content analysis method to analyze the "Macao Special Administrative Region Elderly Security Mechanism and Ten-Year Action Plan for Elderly Services from 2016 to 2025".

Piezoelectric Micromachined Ultrasound Transducer Technology: Recent Advances and Applications.

The objective of this article is to review the recent advancement in piezoelectric micromachined ultrasound transducer (PMUT) technology and the associated piezoelectric materials, device fabrication and characterization, as well as applications. PMUT has been an active research topic since the late 1990s because of the ultrasound application needs of low cost large 2D arrays, and the promising progresses on piezoelectric thin films, semiconductors, and micro/nano-electromechanical system technology. However, the industrial and medical applications of PMUTs have not been very significant until the recent success of PMUT based fingerprint sensing, which inspired growing interests in PMUT research and development.

Enhanced Properties of 3-MHz Sliver-Mode Vibrators for Cardiac Probes With Alternating Current Poling for Pb(MgNb)O-PbTiO Single Crystals.

We investigated the effects of alternating current poling (ACP) on the piezoelectric and dielectric properties of 3-MHz sliver mode (L13 mm × W0.10-0.25 mm × T0.

A Review on Alternating Current Poling for Perovskite Relaxor-PbTiO Single Crystals.

With the great success on verifying its effectiveness on relaxor-PbTiO3 (PT) single crystals (SCs), alternating current poling (ACP) has been taking a center as a new domain engineering method in the last few years. Compared with the conventional direct current poling (DCP), ACP enables enhanced piezoelectric and dielectric properties. In this article, research progress in ACP and perspectives are introduced.

A Review of Lead Perovskite Piezoelectric Single Crystals and Their Medical Transducers Application.

Piezoelectric materials have been developed since early 1900s and many research had been conducted on the composition and process to obtain higher piezoelectric constants ( d ). Within composition research, lead perovskite relaxor piezoelectric single crystals (SCs) of Pb(Mg1/3Nb2/3)O3-lead titanate PbTiO3 type have been actively studied since 1990s because of their outstanding pC/N compared with those of the conventional Pb(Zr,Ti)O3 ceramics. A major driving force of these SC research has been promoted by mass production of ultrasound transducers and array probes for medical diagnostic systems since early 2000s.
