Technology is evolving with time and generations. Now, there is a smarter way to heal your wounds. You don’t’ need to apply creams and bandages. There is an electrically conductive hydrogel that could cure the wound within a limited period of time. The stretch and sticky material contain small electronics devices. The tiny reservoirs that make up the devices can also store medication.
Most of the people or the users considered it equivalent to a Smart “Band-aid”. The hydrogel and embedded sensors would work together to wrap and treat the wound. When the dressing is applied to a highly flexible area, such as the elbow or knee, it stretches with the body, keeping the embedded electronics functional and intact.
This design strategy is used for robust hydrogels that mix water with a small number of selected biopolymers for the creation of soft, stretchy materials with a stiffness of 10 to 100 kilopascals — about the range of human soft tissues. Also, there is a method that can strongly bond the hydrogel to various nonporous surfaces.
It contains a unique capability that when a sensor senses something different, like an abnormal increase in temperature, the device can on demand release drugs to that specific location and select a specific drug from one of the reservoirs, which can diffuse in the hydrogel matrix for sustained release over time.
