Smart Bandage capable of detecting bedsores at a very early stage
Bedsores and ulcers can be a real irritation for bed-ridden people, and they are very painful indeed. To counter this problem Engineers at UC Berkeley and researchers at UCSF are in the phase of developing a Smart Bandage that detects underlying development of bedsores at a very early stage. The development of this Smart Bandage is undertaken by UC Berkeley researchers who devised the software and hardware of the bandage, while UCSF carried out all the initial animal trials. Smart Bandage uses electrical signals (impedance spectroscopy) to detect tissue development under the skin for curing bedsores or ulcers at their root level.
The flexible electronics are embedded on the bandage in the form of gold electrodes on thin piece of plastic. Using impedance spectroscopy, the researchers are able to detect the flow of current through the cells. If the current is being resisted, it is a tell-tale sign of healthy tissue since it doesn’t allow flow of current, whereas if there is flow of electric current, the cell wall is damaged. A test conducted on rats showed that the smart bandage was able to detect any development of cell damage consistently.
The smart bandage has a whole lot of applications in the future as it can be used for reporting the recovery of tissue damage. This will help doctors and physicians in getting a good idea about patient’s recovery time, and improving patient care drastically.
