"In this talk Anna shares the latest innovation in bionics from her lab."
Via Wayne Radinsky, who wrote: "Artificial skin with 3 senses: touch (force),
temperature, and humidity. Works by combining a thin film material that changes
shape in response to force, temperature, or humidity with a piezoelectric
material that senses the change in shape and turns it into an electric current.
There’s 2,000 sensors per square millimeter, with a hydrogel which changes
shape in response to force and temperature, and because of its ability to
absorb water, it changes shape with humidity as well, surrounded by a shell of
piezoelectric zinc oxide.
This is created using a process called chemical vapor deposition (CVD). She
(Anna Maria Coclite) is a CVD expert, but she doesn’t talk about the details
much in this talk. CVD is used primarily in the semiconductor industry. The
main idea is to vaporize a chemical to deposit a thin – 1-atom thick, or
1-molecule thick – layer on a solid surface. A vacuum is created to vaporize
the chemical. And chemicals are chosen so there is a chemical reaction on the
surface. Without this chemical reaction, the process is called “physical vapor
deposition” instead of “chemical vapor deposition”.
She jumps straight to talking about applications of the technology. My first
thought was this could be used for robots, and she mentioned that, but what she
thought would be the primary applications were medical applications, such as
artificial skin for burn victims, and sense of touch for people with
prosthetics."
