Hi everyone,
I wanted to share an open-source hardware initiative developed to provide equitable, non-pharmacological support for agitation and perceptual isolation in dementia care: Project SAVI.
Project Overview:
Traditional palliative interventions often rely heavily on pharmacological sedation, which carries debilitating functional side effects. SAVI is engineered as a low-cost, non-invasive alternative built around sensory stimulation and a strict $15 Target BOM.
Key Technical Aspects:
- Acoustic-Haptic Transduction: Captures familiar acoustic resonances and vocal timbres (85 Hz – 255 Hz) and transduces them into somatosensory cutaneous vibrations (150 Hz – 300 Hz) targeting Pacinian corpuscles.
- Microcontroller: ESP32-based open architecture.
- Eco-Kinetic Integration: A zero-power complementary glove design utilizing ambient kinetic energy and micro-currents.
- Open Governance: Licensed under CERN-OHL-P v2 (Hardware) and MIT (Firmware).
Research Documentation & DOI:
The full methodology and somatic anchoring paradigms are published as open preprints via Figshare:
- Primary Architecture DOI: https://doi.org/10.6084/m9.figshare.34002294
- GitHub Repository: GitHub - sutharsan-gahm/project-savi: Open-Hardware Neuro-Safety Architecture & Eco-Epigenetic Haptic Conditioning Framework (CERN-OHL-P & MIT Licensed) · GitHub
- ORCID: 0009-0003-7103-446X
I am actively looking for feedback from the open hardware community, academic researchers, and potential collaborators interested in pilot trials or frugal biomedical hardware development.
Looking forward to your thoughts and critique!
