Scientists have introduced a promising technology aimed at improving the treatment of chronic wounds and ulcers, a development highlighted by the press service at Chalmers University of Technology. The advance centers on harnessing electrical stimulation to influence the healing process in damaged skin. This approach emerges as a potential option for people who struggle with healing due to health conditions that compromise skin integrity, offering a new avenue beyond standard wound care practices.

In healthy individuals, most skin injuries mend with little intervention, though scars often remain as a reminder of the event. Yet for patients with diabetes, spinal cord injuries, or circulatory issues, the natural repair process can falter. The consequence is a higher susceptibility to infections, a risk of tissue death, and in severe cases, the loss of a limb. The new method seeks to address these challenges by optimizing the wound-healing environment through carefully controlled electrical cues. [Source: Chalmers University of Technology]
Led by Maria Asplund and collaborators, the team focused on directing cell movement using an electrical field. It is known from basic biology that skin cells respond to electrical gradients, guiding their migration and organization. The challenge lies in steering this response with precision so that cells move toward the wound and promote faster re-epithelialization without causing disarray in the healing tissue. The researchers built a platform that allows precise manipulation of the cellular microenvironment, enabling a more predictable healing trajectory. [Source: Chalmers University of Technology]
In their experiments, the scientists created a biochip that hosts cultured skin cells and generates tiny, controlled wounds. When an electric field is applied to the wounded area, the cells align their movement along the field lines, accelerating closure. Remarkably, wounds treated with this electrical stimulation healed about three times faster than untreated controls in the same setup, suggesting a meaningful impact on wound remediation. The work emphasizes how electrical cues can coordinate cellular activity to streamline the repair process. [Source: Chalmers University of Technology]
The study also explored how varying the stimulus can influence outcomes. When simulating diabetic skin lesions, electrical stimulation achieved a healing pattern approaching that of uninjured skin. Importantly, the voltages used remained low, under 200 millivolts, reducing the risk of cellular damage and preserving tissue integrity. The key finding is that customization matters: tailoring stimulation parameters to each wound can maximize the therapeutic effect while protecting cells. [Source: Chalmers University of Technology]
Beyond the fresh data, the researchers connect their findings to broader biological principles. They point out that electrical fields can direct collective cell behavior, a concept with potential applications in regenerative medicine and tissue engineering. The work adds a practical dimension to the understanding of how physical cues, not just chemical signals, shape the dynamics of wound repair. The ultimate goal is to translate this approach into clinically feasible therapies that improve outcomes for individuals with chronic wounds. [Source: Chalmers University of Technology]
