Abstract: Provided is a transdermal microneedle array patch, including: a bottom cover; a top cover; a substrate disposed within the top cover; and a first probe and a second probe disposed between the bottom cover and the top cover and electrically connected the substrate. The first and second probes form an open circuit. While the bottom cover is combined with the top cover to form the transdermal microneedle array patch, the first and second probes form a closed circuit.

Abstract: The present invention provides a soybean based non-toxic, non-hazardous, user and environmentally friendly odor trapping composition matter as a toilet spray. This product not only limits the undesired smell from defecation and releases a desirable smell, but also has potential antimicrobial properties to sanitize the toilet bowl.
