1/ AI use method: bristle-level contact sensing and AI-based classification
2/ Application task: evaluation of toothbrush contact conditions
3/ Reported result: reported as a system that recognizes tooth contact and evaluates brushing
4/ Within this period (2026-09-28~2026-10-12), no item that could be definitively adopted as a new issue in the materials science field was identified.
5/ Nature Communications' DigiDent is known as a dental research study that combines bristle-level sensing and AI to evaluate brushing contact, but based on publicly available information alone, it was not appropriate to classify it as a new issue in the fields of materials·battery·semiconductor·polymer·catalyst·MI/autonomous laboratory.
6/ In addition, it was difficult to sufficiently cross-verify the abstract, publication date, and results from publicly available information alone.
7/ Therefore, no verified new materials issue was included in this list.
8/ This judgment is a classification result within the verifiable scope, and cases with insufficient public information were excluded. [1][2]

No verified new issues: No items identified for adoption as new materials·AI news during this period
No additional verified new materials·AI issues were identified during this period. Among the leads provided, DigiDent is an example of using AI for dental contact-recognition evaluation, but there was insufficient basis to treat it as a new issue in the materials science category, and it was difficult to cross-verify the results from publicly available information alone.

How to apply this
You can test the principle of classifying surface contact states using contact sensor data and machine learning.
- Prepare surfaces or specimens with different contact states and collect sensor outputs together.
- Organize the sensor signals into time windows and split them into training, validation, and test sets.
- Train a classification model and then evaluate performance on an independent test set.
- Check generalizability through additional tests that change the sensor position or surface conditions.
- Data needed
- You need sensor time-series data in which surface contact can be distinguished, together with the corresponding ground-truth labels.
- Checking the result
- Check classification accuracy, recall, and the confusion matrix on new samples, and see whether performance is maintained even when the sensor layout changes.
- What can go wrong
- If the training data are biased toward a specific sensor layout or usage condition, performance may drop sharply in real usage environments.
