“…This section summarises the electronic circuitry currently available for this purpose which has been examined by a number of researchers. 90,93,115,116 The material is presented in two subsections where the rst section considers simple temperature cycling while the second considers systems based on Olsen-type cycles where electrical energy is input into each cycle. Having converted thermal energy into electrical energy (charge) it is necessary to transfer the electrical energy to an external load (e.g.…”

This review covers energy harvesting technologies associated with pyroelectric materials and systems. Such materials have the potential to generate electrical power from thermal fluctuations and is a less well explored form of thermal energy harvesting than thermoelectric systems. The pyroelectric effect and potential thermal and electric field cycles for energy harvesting are explored. Materials of interest are discussed and pyroelectric architectures and systems that can be employed to improve device performance, such as frequency and power level, are described. In addition to the solid materials employed, the appropriate pyroelectric harvesting circuits to condition and store the electrical power are discussed.

“…Kandilian et al (2011) showed that maximum energy density of 100 mJ cm −3 per cycle between temperatures of 80°C and 170°C by commercial PMN–32PT capacitors subjected to the Olsen cycle. Amokrane et al (2012) showed a rectifier-generated voltages—using comparators and MOSFET as diodes—ranging from 0.8 to 2.5 V which is higher than those obtained with conventional rectifiers. Sebald et al (2008) studied methods for optimizing pyroelectric energy harvesting and described the most important parameters when choosing materials and designing a device.…”

The purpose of this work is to demonstrate a new simple stand-alone method of characterizing the impedance of a pyroelectric cell. This method utilizes a pyroelectric single pole low-pass filter technique. Utilizing the properties of a pyroelectric single pole low-pass filter technique, a known input voltage is applied and using simple equations, capacitance Cp and resistance Rp at a frequency range of 1 mHz to 1 Hz can be calculated. For verification purposes, an LCR meter and an impedance analyzer were exploited at 10 and 100 Hz, respectively. Results showed that Rp values for two materials, lead zirconate titanate-5A and polyvinylidene difluoride, were within 8%, and Cp values were within 7.5%. In addition, to verify the importance of the impedance values in energy harvesting applications, output power was measured with varying impedance values. The optimal load resistances for polyvinylidene difluoride and lead zirconate titanate-5A were consistent with the measured pyroelectric impedance at the particular heat range with 10.9% and 1.4%, respectively. The pyroelectric single pole low-pass filter method presented here demonstrates that for pyroelectric materials the impedance depends on two major factors: (1) average working temperature and (2) the heating rate. Neglecting these two factors can result in inefficient and unpredictable behavior of pyroelectric materials when used in energy harvesting applications.

“…There are two kinds of RF/DC rectifier: the half wave rectifier [9] and the full wave rectifier [10]. The double diode rectifier is very interesting because it's a full wave rectifier and is compact compared to other rectifier structures [11]- [12]. We can also notice that we use a minimum of 2 diodes for a full wave rectifier.…”
