Abstract

Objectives: To explore the effectivity of natural hydrogels for controlling the microfluidic flow in smart bandages. Worldwide, several researchers are trying to develop smart bandage having the capabilities of controlled amount of automatic drug flow to the wound, but the complexity of the required mechatronics does not allow the size of the bandage to be easily wearable. Method: The drug flow within the microchannels of the bandage is controlled using easily available hydro sensitive seeds (Plantago ovato and Salvia hispanica L). On placing the seeds within the microchannels, the investigations showed that the water content within the drug is slowly absorbed by the seeds and the flow of drug is restricted within the channel leading to the controlled flow in a small passage of time. Findings: Plantago ovato and Salvia hispanica L. as natural hydrogels show effective control of the flow rate required for smart bandages. The analysis of the results shows that Salvia hispanica L. can efficiently be used for controlling the drug flow within the microchannels and Plantago ovato for absorbing residue within the sink of the bandage. Novelty: The main problem of the smart bandages developed in some of the labs is the complexity of the design used for controlling the drug flow. The novelty of the proposed smart bandage is its low cost design and efficiency of automatic regulating drug flow without the use of complicated electronics.
