“…To further investigate the phase characterization of our BaTiO 3 thin film, we performed the Raman analysis with a 514.5 nm Ar+ laser line as the excitation source. Figure d shows the Raman spectra of the piezoelectric BaTiO 3 thin film with the peaks at ≈305 and ≈720 cm −1 , which indicated the E, B 1 (transverse optical [TO] + longitudinal optical [LO]) and E, A 1 (LO) modes, respectively: These modes revealed that the BaTiO 3 thin film subjected to high temperature annealing consists of a perovskite tetragonal phase …”

“…The advent of a flexible piezoelectric energy harvester (f‐PEH) will be a great innovation in a self‐powered system, which enables the operation of commercial electronic devices and the sensing/monitoring of biomechanical motions . To demonstrate the mechanically flexible and robust energy device, a variety of piezoelectric nanomaterials, such as 0D nanoparticles, 1D nanowires/nanotubes/arrays, 2D nanosheets, and thin films, have been used based on ZnO, BaTiO 3 , PbZrTiO 3 (PZT), Pb(Mg 1/3 Nb 2/3 )O 3 –PbTiO 3 (PMN‐PT), (1− x )Pb(Mg 1/3 Nb 2/3 )O 3 –( x ) Pb(Zr,Ti)O 3 (PMN‐PZT), 0.5(Ba 0.7 Ca 0.3 )TiO 3 –0.5Ba(Zr 0.2 Ti 0.8 )O 3 (BCTZ), MoS 2 , and boron nitride (BN) by many researchers in the past few years.

“…A single IDE model with the two lateral electrodes on the piezo‐ceramic was bent with a bending radius ( R c ) of 0.83 cm, which was corresponding to the displacement of 5 mm from an original 3 cm long plastic substrate. We used the each material parameters of piezoelectric BaTiO 3 (an elastic modulus of E = 67 GPa, a piezoelectric charge constant of d 31 = 78 pC N −1 , a mass density of ρ = 5700 kg m −3 , and a dielectric constant of K T = 1450) provided by the simulation software (COMSOL v5.4) . To determine the effective strain induced in the BaTiO 3 layer, we calculated the distance ( h neutral ) from the top surface of the f‐PEH to the mechanical neutral plane by Equation as follows

h_{neutral} = \frac{\sum_{i = 1}^{N} {\overset{E}{true}}_{i} \times t_{i} (\sum_{j = 1}^{i} t_{j} - \frac{t_{i}}{2})}{\sum_{i = 1}^{N} {\overset{E}{true}}_{i} \times t_{i}}

where N, t i , and

{\overset{E}{true}}_{i}

are the total number of layers, thickness of the i th layer from the top surface, and effective elastic modulus, respectively.…”

Flexible piezoelectric energy harvesters (f‐PEHs) have exhibited significant potential as long‐lasting self‐powered sources or sensor devices, as they can generate reliable and repeatable electricity under harsh and tiny mechanical bending cycles without restraints anywhere and anytime. Herein, a new approach for transferring piezoelectric ceramic thin films onto a single flexible substrate via piecemeal elimination of the sacrificial mica substrates is proposed. The crystallized piezoelectric BaTiO3 thin film on a rigid mica substrate with electrodes and passivation layers is peeled off by means of a physical delamination process using sticky tape as the remover. The film is then transferred onto a flexible polyimide substrate using a polymer elastomer as a support. The fabricated BaTiO3 thin‐film f‐PEH successfully converts an open‐circuit voltage of ≈0.5 V and a short‐circuit current of ≈30 nA from repeated mechanical bending deformations. The energy generation mechanism and performance of the perovskite BaTiO3 thin‐film f‐PEH is supported using finite‐element analysis (FEA) with multiphysics simulations. The novel transfer techniques adopting the removal of sacrificial mica layers opens the door to various high‐performance flexible and wearable applications based on all‐inorganic materials.

Human-integrated devices include wearable and implantable devices for monitoring vital human signals or interacting with the human body. [1-3] The human-integrated devices needed to be tethered to the organs or the human skin for implementing their functions such as sensing and energy harvesting. [4-18] The economical, agile, customizable manufacturing, and integration of multifunctional device modules into networked systems with mechanical compliance and robustness will enable unprecedented human-integrated smart wearables [19-23] and usher in exciting opportunities in emerging technologies such as electronics, [24-29] wearable computation, [30-36] human-machine interface, [37-42] robotics, [43-48] and advanced healthcare. [49-54] The fabrication of stateof-the-art microelectronics involves hightemperature processing steps, which are generally incompatible with the flexible substrates (e.g., paper, polymer, fiber, etc.) [55-61] widely used in the wearable devices. Moreover, the current microfabrication technologies are not well positioned to process the emerging functional nanomaterials (e.g., nanowires [NWs] and 2D materials). [62-65] Such incomparability severely limits the pace of deploying these emerging materials (despite their unprecedented properties) in wearable and flexible device technologies. The additive manufacturing (AM) processes have emerged as potential candidates for addressing the earlier limitations of the current microfabrication technologies in fabricating flexible/wearable printed devices with diversified functionalities, e.g., energy harvesting/storage, sensing, actuation, and computation, leveraging advantages such as maskless processing, versatile ink formulation, low cost, low processing temperature, and scalability. [66-71] Researchers have devoted tremendous efforts to develop the related technologies, and several reviews have provided excellent discussions on the material formulation and process aspects of AM techniques. [63,72-79] However, to our best knowledge, there are few review reports about the ink-based additive nanomanufacturing of functional materials for human-integrated smart wearables. To fill this gap, here we review the recent progress in ink-based

Among the various forms of natural energies, heat is the most prevalent and least harvested energy. Scavenging and detecting stray thermal energy for conversion into electrical energy can provide a cost-effective and reliable energy source for modern electrical appliances and sensor applications. Along with this, flexible devices have attracted considerable attention in scientific and industrial communities as wearable and implantable harvesters in addition to traditional thermal sensor applications. This review mainly discusses thermal energy conversion through pyroelectric phenomena in various lead-free as well as lead-based ceramics and polymers for flexible pyroelectric energy harvesting and sensor applications. The corresponding thermodynamic heat cycles and figures of merit of the pyroelectric materials for energy harvesting and heat sensing applications are also briefly discussed. Moreover, this study provides guidance on designing pyroelectric materials for flexible pyroelectric and hybrid energy harvesting.
