Personal care devices are often exposed to water and other fluids during everyday use. Preventing fluid ingress is essential to maintaining device performance, reliability, and a positive user experience over time.
However, achieving effective sealing can be challenging in compact device designs, particularly around moving components, narrow gaps, and areas with limited space. Conventional sealing solutions, such as assembled rubber-based seals, can be difficult to integrate under these conditions, creating a need for alternative approaches for fluid protection.
We are looking for a fluid material and application process (e.g., injection, precision dispensing, capillary application) that can create a flexible sealing/fluid barrier in specific areas of an already assembled personal care device, particularly in gaps of 1 mm – 3 mm between moving and fixed components.
- Self-expanding flexible foam sealing materials
- Low-modulus silicone and polymer gel sealants
- Non-curing viscoelastic sealing compounds
- In-situ curing flexible elastomeric sealants
- Self-healing or re-formable sealing materials
- Applicable to an already assembled device and form an effective fluid barrier across gaps of 1–3 mm between moving and fixed components
- Maintains an effective fluid barrier around components moving up to ±1 mm at 160 Hz, with minimal damping or interference with movement, over 12 hours of cumulative, intermittent operation
- Safe for human contact (e.g., food-contact applications) and resistant to exposure to common personal care products
- Commercially available solutions requiring minimal additional development or adaptation
- Scalable solutions or already available in bulk quantities
- Suitable for medical applications or compliant with relevant FDA regulations
- Materials that cannot meet human safety requirements or lack a realistic pathway to regulatory approval
- Early-stage concepts or ideas in fundamental research
- Preformed sealing components with fixed geometries, such as O-rings and conventional gaskets
