Existing biomedical imaging modalities are often restricted by their substantial size, high costs, and potential risks associated with ionizing radiation exposure. Given these challenges, there is an urgent need for innovative imaging systems that not only excel in detection performance but are also compact, cost-effective, and ensure safety for biomedical applications. In response to these requirements, our research introduces an advanced terahertz (THz) microbolometer array imaging system (MAIS), specifically engineered for biomedical detection. At the core of this system is our novel microbolometer, which is distinguished by its unique structure and integration with graphene
its innovative design and strategic material composition substantially enhance the MAIS's efficacy. This graphene-integrated microbolometer demonstrates outstanding performance within the 1-5 THz operational bandwidth, achieving an average response time of 0.246 s, a peak responsivity of 8.95 × 10
