Abstract
Described herein is using an array of microelectromechanical systems (MEMS) oscillators to produce unique identifiers. At least some of the MEMS oscillators will “couple” or influence each other when exposed to an external stimulus, such that the frequency of the device is not equal to the combination of individual MEMS oscillator frequencies. The frequency of the device provides a unique “fingerprint” that allows the device to be identified with accuracy but is incredibly difficult to copy, meaning the response may be a physical unclonable function (PUF).
Claims15
A method of creating a unique identifier, the method comprising:
- fabricating a plurality of oscillators;
- adhering a weight on at least one oscillator within the plurality of oscillators;
- and
- recognizing a response of the plurality of oscillators as the unique identifier;
- wherein:
- the plurality of oscillators comprises at least one of a cantilever or a bridge,
- the weight adheres to at least one of the oscillators within the plurality of oscillators, and
- the response comprises the frequency of the plurality of oscillators.
A device for creating a unique identifier, the device comprising:
- a plurality of oscillators;
- and
- a weight attached to at least one oscillator within the plurality of oscillators;
- wherein:
- the device is configured to generate a frequency response as a result of an external stimulus, and
- the frequency response is the unique identifier.
