ABSTRACT: Advances in piezoelectric or triboelectric materials have enabled high frequency platforms for mechanical energy harvesting (> 10 Hz), however virtually all human motions occur below 5 Hz and therefore limits application of these harvesting platforms to human motions. Here we demonstrate a device configuration based on sodiated black phosphorus nanosheets, or phosphorene, where mechano-electrochemical stress-voltage coupling in this material is capable of efficient energy harvesting at frequencies as low as 0.01 Hz. The harvester is tested using both bending and pressing mechanical impulses with peak power delivery of ~42 nW/cm2 and total harvested energy of 0.203 µJ/cm2 in bending mode and ~9 nW/cm2 and 0.792 µJ/cm2 in pressing mode. Our work broadly demonstrates how 2D materials can be effectively leveraged as building blocks in strategies for efficient electrochemical strain energy harvesting.

An ambient mechanical energy harvester converts input mechanical energy into electrical energy, which can be transferred and utilized in other systems.1-2 Conventional methods of ambient mechanical energy harvesting commonly utilize a variety of piezoelectric and triboelectric materials.3-5 Although these materials are capable of effective energy harvesting at high frequencies (>10 Hz), their performance drastically drops when these devices are operated under low frequency ( 30%, Figure S8, see supporting information), lack of understanding of the mechanical properties in both 2D materials and ion-intercalated 2D materials remains a bottleneck toward robust quantitative assessment. At the systems level, one can infer that control of assembly of the nanostructured building blocks will be a critical factor to enable efficient coupling of mechanical energy to electrical energy. At the nanoscale, one can envision a new class of strain harvesters that can be assembled at the singlenanosheet scale. A simple example is a stacked 2D material with locally intercalated ions10, 22, 32 that can function as a nanoscale strain harvesting device for low-frequency motions at the molecular scale in fabrics, liquids, or other media. Our work emphasizes how 2D building blocks are platforms for the design of future strain energy harvesting schemes tuned to harvest energy from low frequency motions.

In summary, our work demonstrates a 2D material (phosphorene) strain energy harvester configuration relying on mechano-electrochemical stress-voltage coupling at low frequencies relevant to human motions. The assembled harvester was tested in both bending and pressing modes, with experiments demonstrating a peak power delivery of ~42 nW/cm2 (0.1 Hz, RoC = 3 mm) and ~9 nW/cm2 (0.1/0.01 Hz, Load ~0.2 MPa) respectively. The energy output from these devices during bending and pressing were 0.203 µJ/cm2 (0.1 Hz, RoC = 3mm) and 0.792 µJ/cm2 (0.01 Hz, Load ~0.2 MPa) respectively with response times (FWHM of current output – 10 s and 100 s) several orders of magnitude greater than conventional piezoelectric systems which provide highly inefficient harvesting capability at such low frequencies. This provides a framework to exploit (i) the controlled mechanical properties of 2D materials, (ii) the homogenous strain propagation that occurs in 2D material geometries, and (iii) the capability of accessing 2D material energy harvesting tuned to frequencies relevant to human motions. Our results support future work spanning from harvesting mechanical stresses at the nanometer length scales in designer 2D material stacks to designing system-level architectures, such as integrated MEMS-electrochemical harvesting units
