One Sensor, Multiple Research Lenses

Care Motion is a compact vibration and accelerometry sensor designed to detect motion events from objects it is attached to — without any camera, microphone, or participant interaction. Hanging from a mattress edge or adhered to a cabinet, it becomes a silent, continuous observer.

The same hardware, deployed differently, captures fundamentally distinct behavioral data streams — making it an exceptionally versatile tool across research domains.

Deployment Scenarios

Mattress Deployment
Sleep
Detects bed entry and exit events to compute sleep onset time, wake time, total sleep duration, and number of nocturnal exits.
Refrigerator Door
Eating
Opening frequency and timing patterns provide a proxy for meal regularity and appetite changes over weeks and months.
Medication Bottle
Adherence
Precisely timestamps each interaction with a medication container — an objective, unobtrusive adherence measure for clinical studies.

Why This Matters for Research

Unobtrusive by design. Care Motion collects data passively — no wearables, no cameras, no scheduled check-ins. Participants simply live their lives, and the sensor observes without interruption.

Low cost, flexible deployment. A single, affordable sensor type adapts to entirely different research questions depending on placement. Teams can instrument multiple household objects within a modest budget.

An accessible entry point for early-stage research. Before committing to larger study infrastructure, Care Motion lets researchers test hypotheses in real-world settings with minimal setup — lowering the barrier to field research at any scale.

Longitudinal depth without participant effort. Continuous passive monitoring over weeks or months yields a behavioral record that self-report and short-term observation simply cannot match — all without placing any ongoing burden on participants.
