Tiny dressings that generate electricity in response to movement could accelerate wound healing and tissue regeneration. Scientists in Taiwan reviewed the latest advances and potential applications of wound healing technology in the journal Science and Technology of Advanced Materials

The natural wound healing process involves complex interactions between ions, cells, blood vessels, genes and the immune system; with every player triggered by a sequence of molecular events. An integral part of this process involves the generation of a weak electric field by the damaged epithelium – the layer of cells covering tissue. The electric field forms as a result of an ion gradient in the wound bed, which plays an important role in directing cell migration and promoting blood vessel formation in the area.

Scientists discovered in the mid- to late-1900s that stimulating tissue with an electric field could improve wound healing. Current research in this field is now focused on developing small, wearable, and inexpensive patches that aren’t encumbered by external electrical equipment. 

This has led to research on piezoelectric materials, including natural materials like crystals, silk, wood, bone, hair and rubber, and synthetic materials such as quartz analogs, ceramics and polymers. These materials generate an electric current when exposed to mechanical stress. Nanogenerators developed using the synthetic materials are especially promising.

For example, some research teams are exploring the use of self-powered piezoelectric nanogenerators made with zinc oxide nanorods on a polydimethylsiloxane matrix for accelerating wound healing. Zinc oxide has the advantage of being piezoelectric and biocompatible. Other scientists are using scaffolds made from polyurethane and polyvinylidene fluoride (PVDF) due to their high piezoelectricity, chemical stability, ease of manufacturing and biocompatibility. These and other piezoelectric nanogenerators have shown promising results in laboratory and animal studies.

Another type of device, called a triboelectric nanogenerator (TENG), produces an electric current when two interfacing materials come into and out of contact with each other. Scientists have experimented with TENGs that generate electricity from breathing movements, for example, to accelerate wound healing in rats. They have also loaded TENG patches with antibiotics to facilitate wound healing by also treating localized infection.

“Piezoelectric and triboelectric nanogenerators are excellent candidates for self-assisted wound healing due to their light weight, flexibility, elasticity and biocompatibility,” says bioengineer Zong-Hong Lin of the National Tsing Hua University in Taiwan. “But there are still several bottlenecks to their clinical application.” 

For example, they still need to be customized so they are fit-for-size, as wound dimensions vary widely. They also need to be firmly attached without being negatively affected or corroded by the fluids that naturally exude from wounds.

“Our future aim is to develop cost-effective and highly efficient wound dressing systems for practical clinical applications,” says Lin.

Epson Philippines’ partnership with the World Wide Fund for Nature (WWF) Philippines for marine ecosystem restoration has officially kickstarted with a ceremonial launch in Balabac, Palawan. Supported by project stakeholders such as the European Union delegation to the Philippines and local government officials, the project launch highlights the importance of rehabilitating mangrove sites, recognizing their critical role in marine biodiversity and protecting coasts from erosion and storm surges.

Epson, which has previously supported the development of WWF-Philippines’ virtual museum Museo Kalikasan, is now supporting the Mangrove Restoration Project in the municipalities of Balabac and Bataraza, Southern Palawan. As part of the wider European Union-funded Ocean Governance Project—an initiative focused on strengthening habitat resilience through restoration in the Sulu Sulawesi Seascape that covers the Philippines, Indonesia, Malaysia—the joint mission in Palawan aims to boost local capacity in taking care of the mangroves, as well as address other critical issues such as plastic waste management. With Epson as a key partner, the Mangrove Restoration Project was able to expand beyond Balabac and into the neighboring municipality of Bataraza. In addition, the growing relationship between Epson Philippines and WWF-Philippines only further drives Epson Philippines’ commitment to support sustainable innovations and initiatives to solve the world’s greatest challenges.

“Corporations have a shared responsibility in sustainable development,” said Eduardo Bonoan, Epson Philippines’ General Manager for Marketing Division, who shared his remarks virtually during the project launch. “As Epson continues its commitment to sustainable innovation and environmental responsibility, we believe in forming critical partnerships with organizations that are aligned with our values—such as WWF-Philippines.”

To further the goals of the Mangrove Restoration Project, WWF-Philippines will continue to work with local government and key stakeholders such as Epson Philippines to establish a ‘Community Learning and Innovation Hub’ that aims to bridge knowledge gaps and strengthen coastal communities’ experience in resource management, thereby helping to build local capacity.

“It is important that we continue to protect and manage Balabac’s valued mangrove forests to boost our efforts in keeping a healthy environment and supporting local livelihoods,” said Balabac Mayor Shuiab J. Astami, who officially launched the project in Balabac Island.

“We are excited to be part of this multi-stakeholder effort that will restore critical mangroves in Balabac, Palawan and improve the way their coastal resources are managed for the long haul. We strongly hope that this project will succeed and serve as an example for many other communities,” said Executive Director of WWF-Philippines, Katherine Custodio.
