“…The polarization is also gathered from the simultaneous electrical measurement ( P EM ( t )). [ 25 ] In Figure 3 b, the two polarizations, P XRD ( t ) and P EM ( t ), are similar during the D 1 -A period. However, from B to C 3 , the decrease in P EM ( t ) is slower and more linear than the decrease in P XRD ( t ) as a result of electrical losses in the circuit and the internal resistance of the material.…”

“…[ 25 ] The former effect is mainly produced by temperature variation. In the case of a tetragonal crystal structure, the latter is consistent with 90° domain switching, caused by the temperature variations and the external electric fi eld, and 180° domain switching, caused by the electric fi eld.…”

“…Polarization is calculated from the peak intensities of the XRD data ( P XRD ( t )). [25][26][27] This considers only the 90° domain switching as detected by XRD. The polarization is also gathered from the simultaneous electrical measurement ( P EM ( t )).…”

The electrothermodynamic cycle is described by the loop of the electric displacement, D , versus the electric fi eld, E ( D-E loop). In Figure 1 a, a schematic of the theoretical Olsen cycle is presented as ABCD. The cycle begins at a low temperature ( T low ) with no electric fi eld (point A). When the electric fi eld ( E 1 ) is applied, the state moves to point B (path AB), corresponding to the hysteresis loop section of the material obtained at T low (see Figure S1b, Supporting Information), denoting an increase in electric displacement. The temperature is increased to the value T high (path BC). Then, electric displacement corresponds to another hysteresis loop, obtained at T high (point C). Removing the external electric fi eld, the state moves to point D along the hysteresis loop at T high (path CD). Finally, the temperature is decreased to T low , and the state moves to point A (path DA). The produced loop area is considered as an energy density ( N D , the area of the D -E loop); the power density ( P D , = N D f ) is also evaluated from the area. [7][8][9][10][11][12][13][14] To the best of our knowledge, there is no application that satisfi es a true energy breakeven because of the diffi culties associated with fi nding a suitable energy source that can simultaneously give alternative heat and an electric fi eld. [7][8][9][10][11][12][13][14] In this study, a novel electrothermodynamic cycle is presented based on temporal temperature variation to obtain practical net energy from exhaust heat of automobile. Another representative heat electric conversion cycle, the Stirling cycle, is modifi ed, and this cycle has a higher potential than the Olsen cycle. [ 6,7 ] The most representative pyro and piezoelectric material, PZT (C-6, Curie temperature T C : 305 °C), is employed. The temperature variation is considered as a simple pseudo-sinusoidal wave based on the imaging of the temperature fl uctuation of the exhaust gas. An external electric fi eld is applied to the material corresponding to the temperature variation (see details in the Supporting Information). The general Sawyer-Tower (ST) circuit is redesigned by inductions of a Diode and a SWitch (named as DSW circuit, see Figure S2b, Supporting Information) to evaluate the D-E loop and simultaneously harvest the net energy.In Figure 1 a, a schematic of our cycle (ABC 1 D) is shown. The AB path is the same as the Olsen cycle. The material is then isolated and the electric displacement D is kept constant while the temperature is increased to T high . The voltage is increased to the E 2 value (path BC 1 ) based on the electrothermodynamic equation: [ 15,16 ] and p are the electric displacement, electric fi eld, temperature, dielectric permittivity, time, and pyroelectric coeffi cient, respectively (see details in the Supporting Information). Then, the material is reconnected to the circuit, and the state moves to point D (path C 1 D). Finally, temperature is decreased back to T low , and the D-E loop is closed. The triangular area BC 1 C is the additional ...

“…Among the lead-free piezoelectric materials, perovskite structure BaTiO 3 (BT) has been investigated extensively due to its high piezoelectric property, environmental harmony and compatibility with human tissue [6,7]. However, no lead-free materials reported can exhibit more excellent piezoelectric property than that of the PZT materials.…”

“…Activities are ongoing to develop better materials for high precision devices (Hinterstein et al, 2011;Hoffmann & Kungl, 2004). Another topical application is related to the piezoelectric energy harvesting in which a practical way of extracting energy is achievable through the Ericsson energy conversion cycle (Pruvost et al, 2010). Similarly, pyroelectric materials are utilized in infrared radiation detection matrices or pyroelectric energy harvesting components (Olsen & Evans, 1983).…”
