Silly Putty Makes For Super-Sensitive Sensors (popsci.com)
Jonathan Coleman's research group at Trinity College Dublin discovered that Silly Putty "becomes an incredibly sensitive strain detector that can track blood pressure, heart rate, and even a spider's footsteps" when mixed with graphene. Popular Science reports: That graduate student, Connor Boland -- who has since earned his doctorate -- made a batch of graphene in water and added the Silly Putty polymer. As he mixed them, the graphene sheets stuck to the polymer, creating a black goo the researchers dubbed "g-putty." When they ran an electrical current through the g-putty -- graphene-infused polymers can conduct electricity -- they discovered an extraordinary sensitivity. "If you touch it even with the slightest pressure or deformation, the electrical resistance will change significantly," Coleman says. "Even if you stretch or compress the Silly Putty by one percent of its normal size, the electrical resistance will change by a factor of five. And that's a huge change." That change makes g-putty about 500 times more sensitive than other deformation-detecting materials, which would respond to a similar compression with a mere one-percent change in electrical resistance. The results were published in the journal Science.

If you have a stroke whilst wearing some of this as a heart sensor, you will bounce right back up!
Browsing at +1 - no ACs, I ignore their posts. So refreshing!
I can still recall the day I learned that you could copy a frame from the Sunday comics by pressing silly putty onto it. I thought that was the coolest thing ever.
Any time they want to mix it with graphene and inject it into my blood stream, I'm ready. I haven't seen a piece of Silly Putty in decades, but I can still recall its smell vividly. I loved that stuff. I think my childhood dog Smokey ate an entire Silly Putty once and crapped it out unchanged. I think it still had the image of Smokey Stover on it.
You are welcome on my lawn.
But still, very sensitive material that reacts to inputs by a magnitude of 5. I've been married to this material for three decades and didn't know it. Also, graphene (100x strong as steel, magnetic) interlaced by silly putty is a good description of the wife.
