The researchers used a high-speed camera to film how a drop of liquid forms on the tip of an insect’s anal pen and shoots out from there. It turned out that the decline begins at an average rate of 40% higher than the speed of the accelerating organ, namely the anal pen. Thus, insects exhibit a super-repulsive (super-repulsive) mode of movement.
The scientists also evaluated how much sap an insect can absorb on average, as well as metabolic and per shot costs. Excretion of urine in the form of droplets followed by a shot turned out to be energy efficient. It is more efficient than jet formation.
What does this have to do with smartwatches? For example, the Water Lock feature on the Apple Watch can already eliminate water from the device. Engineers can learn from sniper bugs and develop better water spray systems for gadgets.
