“…Relaxor ferroelectric single crystals of (1‐x) Pb(Mg 1/3 Nb 2/3 )O 3 –x PbTiO 3 (PMN–xPT) near the morphotropic phase boundary (MPB) hold promises in non‐resonant actuators, ultrasonic transducers, and energy harvesters due to their excellent electromechanical properties . Various mechanisms are proposed to account for the enhanced piezoelectric response near the MPB, such as complex multiphase structure, increased number of domain variants, and small domain sizes, etc.…”

Multiple phase coexistence contributes to the extraordinary piezoelectric behavior of (1‐x)Pb(Mg1/3Nb2/3)O3–xPbTiO3 (PMN–xPT) near the morphotropic phase boundaries (MPBs). By incorporating an optical path of crossed polarized light (PLM) into the commercialized Piezoelectric Force Microscope (PFM) (named as PLM‐PFM system), in situ domain structure observation from micro‐ to nanoscale, as well as measurement of the piezoelectric behavior for individual domains can be realized. For [001]‐oriented single crystal of 67Pb(Mg1/3Nb2/3)O3‐33PbTiO3 (PMN‐33PT), fine domain boundary structures of rhombohedral (R), tetragonal (T), and monoclinic (M) phases are revealed. Measurements of the electric field‐induced displacement as a function of the applied DC electric field (VDC) are performed for domains with different polarization vectors. Values for the electric field‐induced displacement are in descending order for c‐domains of the M, R, and T phases. For an individual phase of T or M, the displacement increases when the angle between the polarization vector and the applied electric field decreases. The multi‐scale perspective of the domain structures and the corresponding piezoelectric response helps in understanding the ultra‐high piezoelectric performance for PMN‐PT single crystals near MPB.

“…Piezoelectric materials interconvert between electrical and mechanical energy, generating electric charge in response to mechanical stress (the direct piezoelectric effect) and undergoing deformation under an applied field (the converse piezoelectric effect) . Because piezoelectric materials allow direct mechanical to electrical conversion, they find wide use in touch and force sensors, microscale actuators, and related components. Devices utilizing such components have applications in areas from consumer to medical to military. , …”

Interplay among Sequence, Folding Propensity, and Bio-Piezoelectric Response in Short Peptides and Peptoids

Many biomaterials are piezoelectric (i.e., mechanically deform under an applied electric field); however, the molecular origin of this phenomenon remains unclear. In the case of protein-based scaffolds, one possibility involves flexible response of local folding motifs to the applied field. Here, we test this hypothesis by examining the piezoresponse in a series of helical peptide-based oligomers. Control over folding propensity is exerted through systematic variation in both side-chain sequence and backbone composition. Piezoresponse is quantified by piezo-force microscopy on polar self-assembled monolayers. The results indicate backbone rigidity is an important determinant in peptide electromechanical responsiveness.

“…Nah and Zhong (2007) designed a microgripper that achieved a maximum stroke of 170 μm, which can be used for fine positioning. After that, Ciubotariu et al . (2016) designed and tested a pair of cantilevers and believed that the piezoelectric material is a great candidate for precise motion generation while still generating large displacement, as showed in Figure 4(c).…”

Purpose The purpose of this paper is to present state-of-the-art approaches for precise operation of a robotic manipulator on a macro- to micro/nanoscale. Design/methodology/approach This paper first briefly discussed fundamental issues associated with precise operation of a robotic manipulator on a macro- to micro/nanoscale. Second, this paper described and compared the characteristics of basic components (i.e. mechanical parts, actuators, sensors and control algorithm) of the robotic manipulator. Specifically, commonly used mechanisms of the manipulator were classified and analyzed. In addition, intuitive meaning and applications of its actuator explained and compared in details. Moreover, related research studies on general control algorithm and visual control that are used in a robotic manipulator to achieve precise operation have also been discussed. Findings Remarkable achievements in dexterous mechanical design, excellent actuators, accurate perception, optimized control algorithms, etc., have been made in precise operations of a robotic manipulator. Precise operation is critical for dealing with objects which need to be manufactured, modified and assembled. The operational accuracy is directly affected by the performance of mechanical design, actuators, sensors and control algorithms. Therefore, this paper provides a categorization showing the fundamental concepts and applications of these characteristics. Originality/value This paper presents a categorization of the mechanical design, actuators, sensors and control algorithms of robotic manipulators in the macro- to micro/nanofield for precise operation.
