A Portable Power Concept Based on Combustion and Pyroelectric Energy Conversion

Integrated Photothermal‐Pyroelectric Biosensor for Rapid and Point‐of‐Care Diagnosis of Acute Myocardial Infarction: A Convergence of Theoretical Research and Commercialization

“…Furthermore, the pyroelectric mechanism of pyroelectric pervoikte arises from a shift in the spontaneous polarization of certain anisotropic solids in the temperature field, which can replace the traditional Seebeck‐based transducer as a new and simple core of thermoelectric generators. [ 40 ] Meanwhile, pyroelectric pervokite deserves further attention and research due to its strong pyroelectric coefficient and pyroelectric‐induced piezoelectric action of functioning pyroelectric materials. However, there exists regret in the current construction of pyroelectric type of biosensor for biological targets.…”

Graphene oxide/reduced graphene oxide films as protective barriers on lead against differential aeration corrosion induced by water drops

“…3,4 Lead is also used (i) as the electrode material for the electro-reduction of carbon dioxide in aqueous solutions, (ii) as a component to realize piezoceramic devices, (iii) to realize materials with a perovskite structure and (iv) or in soldering technologies. [5][6][7][8][9][10][11][12][13][14] Moreover, thanks to its high density, it is widely used to realize shielding against sound or X-ray radiation. 10 Metallic lead is abundant and malleable.…”

Combustion Power in your Pocket: A Case for Portable Pyroelectric Energy Conversion

“…The generated voltages during rapid heating and cooling can be considerable, and the theoretical Carnot limit of pyroelectric energy conversion has been estimated to be above 80%. 4,5 Despite this, pyroelectrics have been primarily used for sensing applications and have occasionally been incorporated in waste heat-recovery concepts. The use of the pyroelectric effect as a primary energy-conversion mechanism has been rarely considered.…”

“…6 However, if pyroelectric energy conversion is combined with the combustion of energy-dense fuels such as methanol (44 MJ kg À1 ), even low energy-conversion efficiencies result in a comparably accessible electrical power density to state-of-the-art Li-ion batteries ($0.8 MJ kg À1 ). 4 The study by Hanrahan et al introduces a pyroelectric device that relies on a thin film of lanthanum-doped lead zirconium-titanate, also known as PLZT. 4 PLZT is a well-known piezoelectric perovskite featuring a strong pyroelectric coefficient with a Curie temperature that can be tuned via the lanthanum concentration.…”
