Project Objective Our objective was to replicate microfluidics experiments from the paper ‘Venous Materials’ at a larger, more wearable scale, by using molds, silicone, and traditional bonding techniques. We wanted to explore various aesthetic effects of moving liquid from a silicone repository through a set of channels, where the motion would be actuated by physically

Sunjana: It’s been a massive inconvenience having been quarantined and barred from campus facilities from the 12th until the 22nd, however we’re hopeful that we can achieve some meaningful result with the molds we have printed. I took Jina’s design from this morning’s class and turned it into a set of 6 molds, or 3

Sunjana: I was out sick with Covid this whole week, but today I designed some molds that would enable me to do a color overlap using only 2 layers. One layer would consist of the 2 colors (red and blue for example), while the other layer would enable one of the colors (blue) to travel

Sunjana After last week’s failure with the locking mechanism, this week, I attempted to try two locking mechanisms, one with .5mm thick channels, 3 horizontal, 3 vertical, and one with .5mm thick channels, 3 horizontal, 2 vertical. With the first mechanism, I tried bonding using Elmer’s glue, which worked poorly. With the second one, I

This week, Sunjana worked on trying to reverse engineer this locking effect in the Venous Materials paper. It appears that there were 3 layers of pattern involved in this effect: the regular channel connected to the repository at the bottom, the vertical grid channels, and the horizontal grid channels. Sunjana has sent molds of each

For this mold, I decided to experiment with creating a silicone piece that could actually be worn. This piece is designed with a wrist strap that is wrapped in a circle with the edges bonded together. The pulser is situated in the center of the palm and the wearer would press it with their thumb

2/16/22 Possible materials we can use?? DC motor pumps, low power consider how to combine both the liquid actuation and the air Create a glove-like or hand wearable that would actuate when you are about to get a bruise can we certain shapes can be certain colors based on severity of injury Previously focused on

Using soft robotics, I will explore how an audience reacts to a garment that changes color. Drawing inspiration from MIT’s Venous Materials paper, I will create a silicone mold of a glove or mitten that can fit over my hand, with a dark liquid repository in the center of the palm. Additionally, there will be
