Research Roadmap
Document ID RAL-RM-2026.09 · Version 2.0 · 13 September 2026
This page supersedes the prior four-step staging and splits scientific phases from instrument horizons.
A measurement, on this page, is a repeatable mechanical observable with known units, bandwidth, and interrogation depth, and a prospective map into shear modulus G, viscosity η, or frequency-dependent wave speed c(f) and attenuation α(f). It is not a smaller sensor.
Specification of record: Kim (2026),DOI 10.5281/zenodo.22149318. Where this page and the specification differ, the specification governs.
“Mechanical restriction” is a hypothesis-level latent construct, not a measured scalar.
Rex Autistikon Research Foundation, Inc. (operating as Rex Autistikōn Labs) is a 501(c)(3) public charity · 509(a)(2) · EIN 42-3220323. It is not a clinic. It does not diagnose, treat, or license an individual-level score. Partner institutions own human-subjects compliance.
Principles
- Frequency content — the observable must resolve the bandwidth of the hypothesized mechanical filter, not only a single quasi-static reading.
- Depth match — interrogation depth must match the anatomical interface named in the zone dossier.
- Anisotropy — fiber-aligned tissues are not treated as isotropic by default; orientation is recorded.
- Operator independence — hand-circling is not a wavenumber; pose, aperture, and scan path are logged.
- Concordance path — candidate instruments on the same zone are compared before any composite is formed.
- F1–F3 falsification — reliability failure (F1), construct failure (F2), and predictive failure (F3) remain the exit conditions.
Three-layer instrument architecture
Instruments are specified as access, readout, and inverse. This is an instrument stack, not the scientific stack of measurement → representation → transmission. No post-hoc restriction ratio r is computed from these layers.
Access
How energy is delivered to the named interface (actuator, acoustic drive, optical launch, or indentation).
Readout
How motion or strain is recorded (tracking array, optical coherence tomography, shear-wave imaging, coil, or hydrophone).
Inverse
How recorded motion is mapped, prospectively, into G, η, or c(f) and α(f).
- Carbon-nanotube–silicone (CNT–silicone) is a readout-layer strain array around a known actuator, not a source of G.
- Lasers launch or listen only.
- Circular geometry means a fixed annular aperture or a motorized scan with logged pose.
Scientific phases
These five phases replace the former four-step staging. Intervention is not a default next step. The interactive model stays didactic until empirical mechanical inputs replace illustrative sliders.
Phase I — Measurement competence
Active / expandingFor each zone: define the anatomical target, candidate mechanical observables, acquisition method, calibration and quality control, expected ranges, and a test–retest plan. Record explicitly what is not measurable for that zone.
- Zone dossiers in progress for 2, 4, and 6, with later work on 1 and 8 as instruments allow
- Shear-wave elastography protocol development for zone 6
- Collaborator search for optical-coherence-tomography vibrometry at zone 2
Phase II — Mechanical representation
PlanningSpecify how raw measurements map to a common analytical representation (parameters, units, transforms). Assess reliability and, where multiple measures exist, concordance. A transform document is required before any multi-zone composite.
Phase III — Transmission predictions
Conditional on IIApply the computational layer to representations from Phase II. Predictions are outputs, not inputs. Model version identifiers are retained with each run. This phase does not open until Phase II is specified.
Phase IV — Physiological tests
FuturePreregister whether measured mechanical state (and any prospectively defined composite) predicts independent physiological outcomes. Studies run under partner institutional review boards. Partner institutions remain responsible for human-subjects compliance.
Phase V — Intervention-linked studies
Only if warrantedOnly if earlier phases support mechanistic relevance under preregistered criteria. Designs must be able to fail if effects are absent. Targeted fascial interventions in well-characterized cohorts are not a planned default.

| A6 | CNT–silicone strain annulus as receiver only | Surface sites of zones 4 and 6 |
Deliverable. Zone dossiers for 2, 4, and 6; phantom concordance; no new latent score.
Horizon B (3–7 years)

- B6 Gated diaphragm / pelvic MRE
Horizon C (8–15+ years)

- C3 Nitrogen-vacancy nanodiamond as bench calibration, not a zone scanner
- C4 Intra-luminal torsional shear probes
- C5 Acoustoelastic / prestress imaging
- C6 Temporary submucosal micro-electromechanical systems via surgical partners only — the Foundation does not own an implant programme
- C7 Driver-free 7T MRE
- C8 Closed-loop mechanical spectroscopy protocol

24-month workplan
Year 1
- Zone dossiers for 2, 4, and 6
- SWE protocol for zone 6
- OCT-vibrometry collaborator for zone 2
- CNT annulus only as A6 (receiver, not a source of G)
- Do not ingest didactic sliders as data
Year 2
- Phantom concordance of SWE vs MAW vs indentation
- Phase II transform document before any multi-zone composite
- Open Horizon B talks for stretchable ultrasound and orbital MRE
- Update this page if F1 fails
The precise measurement is multi-frequency wave propagation through a geometrically identified interface. Every material and laser is only a way to launch or listen to that wave.
This roadmap is provisional and will be updated as results and collaborations develop. All primary outputs will continue to be released under open-access principles whenever possible.
