IIT Roorkee Researchers Develop Self-Powered Smart Electronic Bandage That Harnesses Body Movement to Accelerate Wound Healing
Roorkee, September 11, 2026: Researchers at the Indian Institute of Technology Roorkee (IIT Roorkee), in collaboration with the Institute of Nano Science and Technology (INST), Mohali, have developed a smart, self-powered electronic bandage that uses natural body movement to generate electrical signals that can support wound healing. The technology is designed to work without a battery, wires or an external power source.
Named 3D-MIDAS (3D Monolithic Integrated Dipolar-Ionic Fibrous Architectural Scaffold), the technology converts mechanical energy generated when its flexible material stretches during natural body movement into electrical stimulation. In simple terms, the movement of the body itself can help generate the electrical output required by the bandage.
What is the 3D-MIDAS electronic bandage?
The newly developed 3D-MIDAS system combines electrically active nanofibres and an ionically conductive network within a single three-dimensional fibrous structure.
When the flexible material is stretched, these components interact to generate electrical signals. The structure is also designed to be porous, breathable and capable of managing wound fluid.
One of the notable properties of the material is its high flexibility. According to the research findings, the scaffold can stretch to approximately 800% of its original length, allowing it to accommodate movement of the body while remaining mechanically functional.
How can body movement help wound healing?
Wound healing is a complex biological process. Natural electrical signals in the body can play a role in guiding cells involved in tissue repair, but these signals can be disrupted when the skin is injured.
The 3D-MIDAS approach is intended to provide electrical stimulation directly at the wound site while using everyday movement as its energy source.
Unlike conventional electrically stimulated wound-healing systems that may require batteries, wires or external equipment, the self-powered approach seeks to reduce dependence on external power.
The researchers believe this combination of mechanical energy harvesting, electrical stimulation, flexible materials and wound-fluid management could provide a foundation for future wearable wound-care technologies.
IIT Roorkee Director highlights societal potential
Prof. K. K. Pant, Director, IIT Roorkee, highlighted the importance of translating advanced research into solutions addressing real-world challenges.
“The real value of research lies in its ability to address challenges that matter to society. This work is a strong example of how advanced materials and interdisciplinary research can be directed towards a practical healthcare need.”
He further noted that using natural body movement to power wound-care technology could be meaningful in situations where flexible and self-powered solutions may offer an advantage.
Research aims to overcome external power limitations
Prof. Kaushik Parida, Principal Investigator, IIT Roorkee, said the research was motivated by the limitations of existing electrical wound-healing systems that depend on external power sources.
“With 3D-MIDAS, the movement of the body itself provides the mechanical energy needed to generate electrical stimulation.”
According to the researcher, the dressing is also designed to be flexible, breathable and capable of managing wound fluid.
The findings suggest that the approach could contribute to the development of more convenient and self-powered wound-care technologies, although further research and clinical validation will be necessary before any routine medical application.
Laboratory studies show higher cell proliferation and migration
The researchers evaluated the technology through laboratory and animal studies.
In laboratory experiments, the 3D-MIDAS scaffold demonstrated approximately three-fold higher cell proliferation and 2.5-fold greater cell migration compared with control conditions.
Cell proliferation and migration are important biological processes involved in tissue repair and wound healing. The results therefore provide preliminary evidence supporting further investigation of the technology.
Animal studies show 90–95% wound closure
In animal studies, wounds treated with the 3D-MIDAS dressing showed approximately 90–95% wound closure within 13–15 days.
The researchers also observed enhanced formation of new blood vessels in the treated wounds.
Histological analysis showed improved tissue architecture and enhanced collagen deposition, findings that are relevant to tissue regeneration and wound repair.
However, these results come from preclinical research and should not be interpreted as evidence that the bandage is already proven for use in humans.
Bandage generates electrical output during natural movement
The team also examined whether the dressing could generate electrical output from natural movement.
For this experiment, the dressing was placed on wounds of freely moving rats. The researchers found that the dressing continued to generate electrical output as the animals moved, without requiring externally applied mechanical stimulation.
This finding is particularly relevant to the self-powered concept behind 3D-MIDAS, as it demonstrates that ordinary movement can provide the mechanical input required for electrical generation in the system.
Stable performance over repeated stretching
The researchers tested the mechanical and electrical stability of the device under repeated deformation.
The device demonstrated stable electrical performance over 500 stretching cycles. Longer-term testing also showed stable performance over three months.
The study additionally evaluated cell compatibility, blood compatibility, inflammatory responses and tissue regeneration, providing a broader assessment of the material's potential as a wound-care platform.
Potential applications in healthcare and emergency settings
The self-powered nature of 3D-MIDAS could potentially be useful in circumstances where carrying batteries, wires or powered stimulation equipment is inconvenient.
Possible future areas include:
- Remote healthcare
- Emergency medical settings
- Disaster-response environments
- Wearable healthcare technologies
- Rehabilitation applications
- Other bioelectronic applications
The technology may also have relevance for demanding field environments, including defence and emergency operations, but the present study does not evaluate military use and no defence application has yet been established.
The researchers emphasise that human clinical studies will be required before the technology can be considered for routine medical use.
Technology could extend beyond wound care
Although the current research focuses on wound healing, the underlying concept could have broader applications.
The combination of wearable sensing, mechanical energy harvesting, flexible materials and bioelectronic stimulation could potentially be explored for other applications where a device needs to operate with limited or no external power.
Further research will determine whether the platform can be adapted for additional healthcare, rehabilitation or wearable applications.
