Company profile
researched Aug 2026Active Protective develops the Tango Belt, a prescription wearable medical device for older adults diagnosed as being at risk of major hip injury from falls. The belt continuously monitors body motion and, when its algorithms recognize a serious hip-impacting fall in progress, deploys a bilateral airbag around the hips to attenuate impact forces that could otherwise cause hip fracture or hip dislocation.
The device is positioned as an adjunct to standard-of-care fall management rather than a replacement for it, and is indicated for prescription use only. Alongside impact mitigation, the system provides caregiver notifications: when configured through a companion mobile application, the belt automatically alerts patient-specified caregivers when a fall is detected, and patients can also trigger a "call button" to request attention.
Business model
Prescription medical device supplied to patients diagnosed at high risk of hip injury, with a companion mobile application for fall notifications and caregiver alerts.
Latest developments
As of the company's July 2026 site update, the Tango Belt is described as an FDA-authorized device (DEN240021) and available by prescription, with a patient qualification tool listed as coming soon.
▸Full profile — market position, technology, go-to-market
Market position
Focused specifically on active mitigation of hip impact during falls, treating patients with diagnosed hip-injury risk rather than only detecting or reporting falls.
Technology
Advanced 3-D motion sensors feed built-in algorithms that continuously monitor motion and are calibrated to trigger only on serious hip-impacting fall motions. On detection, a bilateral airbag deploys in less than 90 milliseconds around the hips. A companion mobile application handles caregiver notifications and a patient-triggered call button.
Go-to-market
Distributed as a prescription-only device, with a prospective-patient qualification pathway and a contact/mailing-list channel on the company website for inquiries and technology updates.
Older adults with a diagnosed risk of major hip injury due to falls, reached via prescribing clinicians, together with their caregivers.
