Overview
The SUNS DV-EBT Electric Toothbrush Pressure Sensing Tester is an engineered metrology system designed specifically for quantitative evaluation of contact force dynamics during powered toothbrush operation. It operates on the principle of high-resolution load cell transduction calibrated to measure axial compressive force in real time as the brush head interacts with standardized test surfaces—simulating gingival and enamel contact conditions. Unlike generic force testers, the DV-EBT integrates motion-synchronized data acquisition to capture transient peak forces, dwell-time profiles, and cycle-to-cycle repeatability under dynamic actuation (e.g., oscillating, rotating, or sonic vibration modes). Its IP67-rated enclosure ensures operational integrity during wet-condition testing, aligning with ISO 20126:2017 requirements for oral care device mechanical validation and supporting compliance-driven development workflows in regulated R&D and QC laboratories.
Key Features
- High-stability precision load cell with full-scale range of 0–1000 g and resolution better than ±0.5 g (typical), traceable to NIST-certified standards via factory calibration certificate.
- IP67-rated stainless-steel and polymer housing enabling submersion testing and resistance to saline, fluoride-containing solutions, and repeated sterilization cycles.
- Motorized vertical actuation stage with programmable stroke depth (0–25 mm) and speed control (0.5–50 mm/s), synchronized with force acquisition at up to 1 kHz sampling rate.
- Dedicated fixture interface compatible with standard brush handle geometries (diameters 22–32 mm) and interchangeable brush-head adapters for multi-brand evaluation (e.g., Oral-B, Philips Sonicare, Colgate).
- Embedded microcontroller with onboard memory for standalone test execution; supports USB-C and Bluetooth 5.0 for configuration and data export without external PC dependency.
- Pre-loaded test protocols aligned with ISO 20126 Annex C (brush head force distribution assessment) and ASTM F2974-21 (performance criteria for powered oral hygiene devices).
Sample Compatibility & Compliance
The DV-EBT accommodates all commercially available rechargeable and battery-operated electric toothbrushes, including oscillating-rotating, sonic, ultrasonic, and pulsating variants. Brush heads are secured using non-slip silicone clamps and torque-limited mounting to prevent slippage-induced measurement artifacts. The system complies with essential safety and electromagnetic compatibility directives applicable to laboratory instrumentation (IEC 61326-1:2013, IEC 61000-6-3:2011). Its force measurement methodology satisfies traceability requirements per ISO/IEC 17025:2017 when used within accredited lab environments. Data records include timestamp, operator ID, environmental temperature/humidity metadata, and digital signature fields to support GLP/GMP audit readiness.
Software & Data Management
SUNS TestSuite™ v3.2 software (Windows/macOS) provides full control, visualization, and reporting functionality. It enables creation of custom test sequences—including ramp-hold-relax profiles, cyclic loading (1–10,000 cycles), and multi-point surface mapping—and exports ASCII CSV, PDF summary reports, and XML datasets compliant with FDA 21 CFR Part 11 for electronic records and signatures. Audit trail logging captures all user actions, parameter modifications, and calibration events with immutable timestamps. Raw force-time waveforms are stored with 16-bit depth and can be post-processed using built-in FFT, derivative, and statistical outlier detection tools.
Applications
- Validation of pressure-sensitive brushing modes (e.g., stall detection, adaptive intensity reduction) per ISO 20126 Clause 7.3.
- Comparative analysis of brush head compliance across product generations or material formulations (e.g., soft-tip vs. tapered bristle arrays).
- Design verification of ergonomic handle force distribution during manual grip + powered actuation.
- Accelerated durability testing of brush head retention mechanisms under repeated axial loading.
- Supporting regulatory submissions to FDA, Health Canada, and EU MDR Annex II technical documentation for Class I/IIa oral hygiene devices.
FAQ
What is the maximum sampling frequency for force data acquisition?
The system acquires force data at up to 1,000 Hz with hardware-triggered synchronization to actuator position and velocity.
Does the DV-EBT support third-party calibration services?
Yes—SUNS provides ISO/IEC 17025-accredited calibration certificates upon request, and the unit features a documented calibration port compatible with standard deadweight and reference load cell systems.
Can test results be integrated into LIMS or MES platforms?
Yes—via RESTful API and OPC UA connectivity options (optional module), enabling automated transfer of pass/fail status, statistical summaries, and raw waveform metadata.
Is firmware upgradable in the field?
Yes—over-the-air (OTA) updates are supported via USB-C or Bluetooth; version history and change logs are maintained in the embedded audit trail.
What environmental conditions are recommended for optimal accuracy?
Operation is specified at 15–30 °C ambient temperature, <70% RH non-condensing; thermal drift compensation is active across this range.
