Abstract

Herein, a portable device for wound healing with self-charging capability has been proposed by utilizing embedded system technology with an electromagnetic energy harvester. With the storing capability, the harvester can generate electricity from human vibration. By enhancing the coil turns and speed of the magnet, the generation rate of the harvester can be increased. The vacuum environment can be easily established by a vacuum pump. According to the negative pressure sensor's data, the environment can be easily stabilized by applying Pulse Width Modulation (PWM) signal to the pump driver. By using adhesive drape, the wound surface can be easily fitted with the fluid container. The device can be used at indoor and outdoor environment uninterruptedly.

Highlights

The large growing old population is teased with an increasing range of acute and chronic, non-healing wounds, generally ascribable to the surge in type 2 diabetes
The inventors of the VacuumAssisted Closure (VAC) technology experimented with pigs and found that the efficient rate of blood flows at the wound surface of the pigs with a -125mmHg vacuum environment but the blood flow gradually decreased within 5-7 min at room pressure at 400 mmHg
The microcontroller is an 8-bit programmable Integrated Circuit (IC) which has a maximum of 20Megahertz (MHz) clock frequency (Makarov et al, 2016) and it was used for data

Summary

INTRODUCTION

The large growing old population is teased with an increasing range of acute and chronic, non-healing wounds, generally ascribable to the surge in type 2 diabetes. VacuumAssisted Closure (VAC) is a highly new technology to manipulate severe and chronic wounds. It is known as many anonyms such as NPWT (Negative pressure wound therapy), TNP (topical negative pressure) SPD (sub-atmospheric pressure) VST (vacuum sealing technique) and so on (Banwell and Téot, 2003). Discontinuous of operation due to the less storage capacity of the devices is responsible for interrupting the wound healing process In this contribution, we present a self-charging portable NPWT device which has the capability of charging itself by harvesting electricity from unused vibration energy
