Biostream Selected for Phase 2 of the DIU AI-Assisted Triage & Treatment Prize Challenge

Biostream, in partnership with Hadean, has been selected to advance to Phase 2 of the DIU AI-Assisted Triage & Treatment Prize Challenge, a programme led by the Defense Innovation Unit to accelerate technologies that support medical decision-making in contested environments.

The challenge seeks to identify portable, network-capable hemodynamic monitoring systems capable of operating in austere and degraded communications environments (DDIL). These technologies are intended to assist medics by improving the early detection and prioritisation of casualties when rapid clinical assessment is difficult.

Key elements of the programme include:

• $999,000 prize pool supporting the development of portable hemodynamic monitoring systems designed for battlefield conditions
• Up to eight finalists invited to demonstrate their solutions during Sword 2026, where systems will be evaluated in operational scenarios
• Top-performing teams may become eligible for a Prototype Other Transaction (OT) contract with the U.S. Department of Defense
• Production requirement that solutions be designed for rapid manufacturing scale, with the ability to support 15,000 units within the first year of deployment
• Joint collaboration between DIU, the U.S. Army Program Executive Office Soldier programme for PM Soldier Medical Devices, and other Department of Defense stakeholders

Biostream is developing a wearable system that continuously monitors physiological signals and uses edge computing to detect patterns associated with medical distress. By combining real-time biosignals with automated alerts, the system aims to support faster triage decisions in environments where medics must operate with limited time and incomplete information.

Selection for Phase 2 places Biostream among a limited group of companies invited to further develop and demonstrate their technology as part of the DIU challenge.

The challenge is part of a broader effort by the U.S. Department of Defense to integrate advanced commercial technologies into defence applications and to strengthen collaboration between the technology sector and the defence community.
