Multifrequency AFM: from origins to convergence

Objetivo: realizar avaliação diagnóstica de condições de vida e saúde dos idosos convivendo em família e comunidade, usuários de uma Unidade Básica de Saúde – UBS e testar o desenvolvimento de uma tecnologia cuidativo-educacional. Metodologia: pesquisa convergente-assistencial, adotando a técnica do grupo de convergência com 13 idosos, que se desenvolveu em sete encontros, em 2013. Resultados: o estudo revelou perspectivas à enfermeira ser facilitadora no desenvolvimento de competências ao autocuidado e estimuladora de idosos para que sejam protagonistas do próprio envelhecimento, instrumentalizada por diretrizes da tecnologia leve de atos de cuidado, fundamentada em referências de enfermagem. Conclusão: o estudo apresentou resultados benéficos aos idosos que se submeteram à experiência e também à enfermagem, pela possibilidade de empreender ações cuidativo-educacionais inovadas.Descritores: Idoso; Tecnologia educacional; Atenção básica; Envelhecimento ativo; Enfermeiro.GROWING THE ELDERLY'S GOOD LIVING AND CARING-EDUCATIONAL TECHNOLOGIES OF NURSING Objective: perform a diagnostic evaluation of living conditions and health of the elderly living in family and community, and users of a Basic Health Unit – UBS, and also test the development of a care-educational technology. Methodology: convergentcare research that adopted the convergence group technique with 13 seniors, which developed during seven meetings in 2013. Results: the paper revealed prospects for the nurse to be a facilitator in the development of self-care skills and stimulate the elderly so that they can be the protagonists of their aging. It was instrumentalized by guidelines of light technology about caring acts based on nursing references. Conclusion: the study presented beneficial results to the elderly who underwent the experience, and also for the nurses, by the possibility of taking innovated caring-educational actions.Descriptors: Elderly; Educational technology; Primary care; Active aging; Nurse.CULTIVO DEL BIENVIVIR DE LOS ANCIANOS Y TECNOLOGÍA CUIDADORA-EDUCACIONAL DE LA ENFERMERÍAObjetivo: realizar una evaluación diagnóstica de las condiciones de vida y salud de los ancianos que conviven en familia, comunidad y son usuarios de una Unidad Básica de Salud – UBS, y testear el desarrollo de una tecnología cuidadora-educacional.

“…Remarkable achievements have been made in AFM since its invention (Binnig, Quate, & Gerber, ). However, most of them focused on improving the scanning speed, enlarging the imaging area, and overcoming limitations of working environment (Santos, Lai, Olukan, & Chiesa, ; Schitter et al, ). Therefore, there are still several issues restricting the application of conventional AFMs, for example, as shown in Figure a, dependence on wire and/or network cable connecting to a computer, and reliance on indoor AC mains supply and low/high‐voltage DC power supply which are generally bulky, making it impossible for conventional AFMs to be miniaturized and work in outdoor or field conditions where no AC electricity is available.…”

This article proposes to develop a WiFi‐controlled portable atomic force microscope (AFM). The AFM consists of a horizontal probe, controlling circuits, digital to analog (D/A) and analog to digital (A/D) interfaces, a microcomputer (Raspberry Pi, RPi), and a laptop. The proposed AFM uses a pocket‐size power supply to drive the controlling circuits, the D/A and A/D interfaces, as well as the RPi that constructs network hotspots and generates scanning signals. With special design and integration of the whole system, both of the AFM probe and electronic controlling system are portable. At a distance of 50 m from the proposed AFM, experiments in the constant height mode and the constant force mode are conducted to evaluate its performance. The results show that this WiFi‐controlled AFM has a maximum scan range of 3.6 × 3.6 μm2 with nanometer order resolution. Meanwhile, it achieves satisfactory image contrast, stability, and repeatability. Compared with conventional AFMs, the AFM proposed in this paper no longer relies on commercial AC mains supply or high‐voltage DC power supply, and realizes WiFi‐controlled AFM scanning and imaging in 50 m or farther without wire or network cable connection to a laptop or a desktop computer. Given credits to these features, WiFi‐controlled AFMs are expected to own a wider range of application, especially in isolated environments, outdoor researches, or even fieldwork investigations.

“…[12][13][14][15][16] Meanwhile, in recent years, multifrequency atomic force microscopy (MF-AFM) has attracted more and more attentions from researchers in this field. 17,18 In spite of the above advances achieved in AM-AFM, however, to the authors' knowledge, AM-AFM based on higher flexural modes of a cantilever has never been specially addressed. This work thus aims at investigating the dynamics of different flexural modes in AM-AFM.…”

Amplitude modulation atomic force microscopy based on higher flexural modes

et al. 2017

In this work, amplitude modulation atomic force microscopy (AM-AFM) based on the higher flexural modes of the microcantilever is investigated by a numerical approach. The amplitude-distance and phase-distance curves for the first four flexural modes are obtained and compared. The dependence of phase on elastic modulus and viscosity of the sample is analyzed. Results show that a higher flexural mode yields a larger amplitude and phase in the repulsive regime and reduces the bistability, but causes a larger sample deformation and peak repulsive force. Compared to that of a lower flexural mode, the phase of a higher flexural mode provides higher sensitivity to viscosity variation for relatively large moduli.
