The 2022 2nd International Conference on Biomedical Engineering Health Care and Disease Prevention (BEHDP 2022) was successfully held during May 28-29, 2022 as a virtual conference due to the growing concerns over the coronavirus outbreak (COVID-19), and in order to protect the well-being of our attendees, partners, and staff as our number one priority.
 BEHDP 2022 is an annual research conference dedicated to smart medicine and health that will bring together scientists, technologists, clinicians and professionals. Hospitals, health systems and pharmaceutical companies around the world are all under the same roof. This conference is supported by numerous universities and research institutes around the world. The focus of this conference is to establish an effective platform for institutions and industries to share ideas and to present the works of scientists, engineers, educators and students from all over the world. The organizing committee of conference is pleased to invite prospective authors to submit their original manuscripts.
 BEHDP 2022 brought together more than 120 researchers in related fields and the conference was divided into three sessions, including oral presentations, keynote speeches, and online Q & A discussion. In the first part, some scholars, whose submissions were selected as the excellent papers, were given about 5-10 minutes to perform their oral presentations one by one. And in the second part, keynote speakers were each allocated 30-40 minutes to hold their speeches. Their insightful speeches had triggered heated discussion in the sessions of the conference.
