A 2010 report said sensors based on single-walled carbon nanotubes could be reset with a flick of a switch. It does not establish how the reset worked, what electrical conditions were used, or whether the result applies beyond the sensors studied.
What did the report claim?
Chemistry World’s news index described single-walled carbon nanotube (SWNT)-based sensors as capable of being “reset” by a simple switch action. The entry was published on 9 September 2010. That is a brief description of a reported research result, not a current product announcement.
Chemistry World is the source of the index entry. Its accessible description does not identify the researchers or the underlying paper, so the claim cannot be tied here to a named team or a specific experiment.

Does “electric shock” mean a household shock?
No such interpretation is supported. “Electric shock” is headline shorthand; the description says only that a switch could reset the sensors. It gives no voltage, pulse, circuit details, or other electrical parameters. It does not describe a household shock or establish that one would be safe or effective.

How did the reset work?
The available description does not explain the mechanism. It does not say what changed in the sensor, what the switch controlled, or whether resetting restored a particular baseline or sensing state. Any detailed account of the physics would go beyond what this source establishes.
What does the report leave unanswered?
- Scope: It does not establish that every SWNT sensor, or nanotube sensors generally, can be reset this way.
- Conditions and repeatability: No test setup, operating conditions, or repeated-use results are provided.
- Performance: The description gives no measurements of sensitivity, accuracy, recovery, or other application-specific outcomes.
- Practical availability: It names no commercial product and does not demonstrate a consumer-ready device.
These details would require the underlying paper or a fuller account of the experiment. The short index description supports the narrow claim of switch-activated resetting, but not broader conclusions about mechanism, performance, or present-day availability.
