Martiii3/NeedleInsertionVibroacousticDataset

Vibroacoustic Needle Insertion Temperature Dataset

This dataset contains vibroacoustic signals from needle insertions into water-saturated porous material.

Structure

• robotic/ - signals from robotic insertions
• manual/ - signals from manual insertions

Each file is a .wav file containing the recorded vibroacoustic signal. Temperature for each signal is included in the filename or metadata. Temperature information is included in each filename in °C.

Data Description and Preprocessing

• Signals represent needle–material vibroacoustic interactions
• Temperature was stabilized using a water bath and verified with an independent probe
• Sampling and acquisition parameters are consistent across recordings

Robotic recordings include pre-insertion, insertion, post-insertion, and withdrawal phases. Only the insertion phase, corresponding to the needle penetration into the material (3.0–4.7 s), was used for analysis.

Manual recordings were trimmed to retain only the segment corresponding to needle penetration inside the material, ensuring comparability with the robotic insertion phase.

Intended Use

This dataset is intended for research on vibroacoustic sensing, temperature regression, and signal-based machine learning methods in minimally invasive procedures.
