Access-H20: Sensor-driven Smart Faucet

Brief Summary

The objective of the SBIR Phase II study is to evaluate the updated Access-H2O™ system, a sensor-driven smart faucet developed during the Phase I SBIR project, to enhance independent drinking and grooming among individuals with spinal cord injury (SCI) in both clinical and home settings. SCI significantly impairs functional independence and the ability to perform activities of daily living (ADLs), with greater loss of function associated with higher and more complete injuries. In particular, individuals with injuries above the C5-C7 level often experience substantial upper extremity impairment, limiting their ability to use their arms and hands for essential tasks such as eating, drinking, and grooming. Access to water is therefore critical for supporting independence and facilitating the successful completion of ADLs in this population. The commercialization of a smart faucet system capable of automatically delivering water at target temperature, flow rate, and nozzle settings tailored to specific ADLs has the potential to substantially improve independence and quality of life for individuals with SCI. The Access-H2O™ faucet was developed and tested during the SBIR Phase I project in 2024 and was subsequently upgraded and refined based on Phase I findings. Participants with SCI, along with control participants, were recruited to evaluate the feasibility and usability of the enhanced faucet system in both clinical and in-home settings. The updated system incorporates voice, motion, and remote-control interfaces to regulate water flow and temperature for ADLs, including drinking, grooming, and washing.
