Physical And Electrical Study Of Aloe Vera Dielectric Layer

Commercially available Aloe vera gel and naturally extracted Aloe vera gel were compared and used as dielectric material in organic electronic device. Commercial Aloe vera and extracted natural Aloe vera layers were formed respectively on aluminum coated glass substrate by screen-printing. Both type...
