Tag and seal employing a micromachine artifact
| DWPI Title: Tamper resistant seal for tamper resistant identification of objects, has multiple particles including micromachine artifact that comprises multiple repeating features which has critical dimension of predetermined value |
| Abstract: A tamper resistant seal including a population of particles embedded in an adhesive, the population including at least one micromachine artifact of a predetermined physical shape. |
| Use: Tamper resistant seal for tamper resistant identification of objects. |
| Novelty: The tamper resistant seal (140) has a frame (150) that is embedded in an adhesive matrix. The frame is of a contiguous material which forms a perimeter that surrounds multiple particles (105). Multiple particles include a micromachine artifact that comprises a material which is selected from a group that consists essentially of monocrystalline or polycrystalline semiconductor material. The micromachine artifact comprises multiple repeating features which has a critical dimension of less than 500 μ m. |
