Alejandra Huerta and Isabela Dominguez envision a future where the shade of your nails can change with a tap of your phone. During Huerta鈥檚 PhD in chemistry, she considered how organic materials could be used to change the colour of cosmetics. But by brainstorming with her sister Dominguez, a computer engineer, they determined that wearable electronics could be a better approach.

In 2019, they participated in McGill Dobson Centre鈥檚听Lean Startup Program,听and placed third in the 鈥淚nnovation Driven Enterprise鈥� category of the McGill Dobson Cup in 2020, the university鈥檚 flagship start-up competition. The prize from the Dobson Cup enabled the sisters to incorporate AIM Colours, through which they are developing ePolish, a wearable, colour-changing artificial nail made of flexible electronic materials. They hope to pilot the product in early 2023.
