“…However, the output performance decreased from PVB‐COO‐Zn 25 due to the decrease in the contact area resulting from the increased pore size in the same area (4 × 4 cm), which hinders triboelectricity due to the decreasing friction area. [ 50 ] The output voltage, output current, and output power density were measured under varying load resistance (Figure 4d ). With the increase in the load resistance, the output voltage increased and the output current decreased.…”

To build devices offering users comfortable experience, it is important to focus on form factor and multifunctionality. In this study, for the first time, multifunctional Zn clusters with shape memory, self‐healing, triboelectricity, and optical sensing synergized with rollable form factor are designed and fabricated by coordinating COO− and Zn2+. As pore forming agent, Zn clusters produce hierarchical porous structure depending on Zn amount. Zn clusters are applied as message transmitters and charge containers in optical sensing and corona charge injection, respectively. Moreover, Zn clusters in PVB‐COO‐Zn serve as positive tribomaterial due to Zn ion doping effect, increasing the output performance as the Zn amount reaches 20 wt%. In addition, injecting positive charge into PVB‐COO‐Zn 20 lead to more than 24 times increase in output performance compared to those of non‐porous structures. The reversibility of Zn clusters endows shape memory and self‐healing, synergized with the rollable form factor. The rollability is implemented using the long alkyl chain and the energy absorption of porous structure, providing damage resistance. The advancements in this work provide opportunities for multifunctional and unique applications (shape memory rotating‐triboelectric nanogenerator, rollable self‐healing touchpad, hidden tag) synergized with rollability that accomplishes working in broadened condition in near future.

“…In recent years, self-powered sensors based on triboelectric nanogenerators (TENGs) have been rapidly developed in wearable and implantable applications. − These kinds of devices have a wide selection of materials, a simple preparation process, a high output voltage, and a low output current. − Driven by external force, their maximum output voltage can reach tens of volts or even hundreds of volts. − The self-powered properties of TENGs based on biodegradable materials have also been demonstrated. − An all-nanofiber, breathable, biodegradable, and antibacterial electronic skin based on TENGs had been prepared and applied for monitoring whole-body physiological signals and joint movement . However, some key challenges of biodegradable TENGs still need to be overcome, such as low sensitivity, poor linearity, and inadequate stability. − In addition, the biocompatibility and biosafety of devices need to be further improved to construct biosensors that can be provided for the diagnosis of diseases in vivo.…”

Bioresorbable electronics that can be absorbed and become a part of the organism after their service life are becoming a trend to avoid secondary invasive surgery. However, the sustainable and secure supply of energy for biosensors is a significant challenge. Here, a bioresorbable pressure sensor (BPS) based on a triboelectric nanogenerator is reported. The BPS based on the triboelectric nanogenerator can directly convert ambient pressure changes into electrical signals. It offers excellent sensitivity (22.61 mV/mmHg), linearity (R 2 = 0.99), and good durability (850,000 cycles). The bioresorbable materials of poly(lactic acid)/ chitosan/sodium alginate in the BPS show great biocompatibility and can achieve 99.99% sterilization for both Gram-positive bacteria and Gram-negative bacteria. In addition, the device can successfully identify an abnormal respiratory event in small animals and will be completely degraded after 21 days. The BPS only employs medical materials used commonly in FDA-approved implants, which is crucial for the biosafety of bioresorbable devices. Triboelectric devices are expected to be applied in the clinic as bioresorbable electronics.

“…All these may finally result in a smaller material footprint of power supply devices and may eventually reduce the problem of electronic waste [ 11 ]. Specifically, cellulose and polysaccharide-based triboelectric nanogenerators (TENGs) [ 12 , 13 , 14 ] and piezoelectric nanogenerators (PENGs) [ 15 , 16 ] have received much attention as potential alternatives to conventional nanogenerators.…”

Natural polymers such as cellulose have interesting tribo- and piezoelectric properties for paper-based energy harvesters, but their low performance in providing sufficient output power is still an impediment to a wider deployment for IoT and other low-power applications. In this study, different types of celluloses were combined with nanosized carbon fillers to investigate their effect on the enhancement of the electrical properties in the final nanogenerator devices. Cellulose pulp (CP), microcrystalline cellulose (MCC) and cellulose nanofibers (CNFs) were blended with carbon black (CB), carbon nanotubes (CNTs) and graphene nanoplatelets (GNPs). The microstructure of the nanocomposite films was characterized by scanning electron and probe microscopies, and the electrical properties were measured macroscopically and at the local scale by piezoresponse force microscopy. The highest generated output voltage in triboelectric mode was obtained from MCC films with CNTs and CB, while the highest piezoelectric voltage was produced in CNF-CNT films. The obtained electrical responses were discussed in relation to the material properties. Analysis of the microscopic response shows that pulp has a higher local piezoelectric d33 coefficient (145 pC/N) than CNF (14 pC/N), while the macroscopic response is greatly influenced by the excitation mode and the effective orientation of the crystals relative to the mechanical stress. The increased electricity produced from cellulose nanocomposites may lead to more efficient and biodegradable nanogenerators.
