Honors Biology Biomimicry 2024

During the mid review, we received one piece of feedback that could improve our project:

Take advantage of the specific hexagonal shape of honey comb cells' property in stacking into each other perfectly while having the most "joints" possible.

We realized this property was a big reason why it is the shape used for honeycomb cells. If it was used for our first prototype, it would have taken a while, but we will use its stacking property for the final product.

Ok we added velcro onto the water tank and the electronics box so that they could attach and detach easily. Then we added wooden sticks and lego pieces so that the solenoid piston could stay in place and its power would be optimized. After we test the leaves tonight, we will stick them onto the wooden rod attached to the piston.

So the superhydrophobic coating and the hydrophilic coating both arrived on Friday, and we worked on finishing the leaves today.

A quick update on the leaves, here's how they are made:

1. laser cut a piece of wood to the correct shape

2. cover the piece with a layer of tin foil (must be very very smooth)

3. spray paint the leaf with hydrophobic paint

4. Use the previous method to make grids of hydrophilic paint on the leaf

With this method, we made 3 leaves that are ready to be tested tonight.
