DARPA News  April 19, 2021 DARPA’s Personalized Protective Biosystem (PPB) aims to address PPE limitations, including threat-specific vulnerabilities, thermal/logistical burdens, and potential exposure risk. The five-year program is divided into two technical areas (TAs). TA1 technologies aim to prevent external contact between the threat and the body, providing 100% survival against more than 10 CB agents with smart, lightweight materials. TA2 technologies will neutralize threats at vulnerable internal tissue barriers (i.e., skin, airway, ocular) using a configurable countermeasure. DARPA recently awarded contracts to develop lightweight materials and adaptable, tissue-protective countermeasures to provide on-demand, broad spectrum, and rapid long-term protection. Performers […]
