Move over cassette tapes, adhesive tape has memory, too
Researchers at Penn State have discovered that ordinary adhesive tape can store multiple adjustable and erasable memories. This innovative material memory allows for the creation of distinct lines of adhesion that can be tuned for strength and erased as needed. The findings could have implications for various applications in materials science and engineering.
- ▪Ordinary adhesive tape can store a sequence of multiple memories that can be fine-tuned and erased.
- ▪The research team developed a device that measures the force required to peel the tape, allowing for memory retrieval.
- ▪The strength of the memories can be adjusted, enabling different amounts of force to be required to peel past each memory line.
