349 ranked journals · Subfield in Engineering
Biomedical Engineering has 349 ranked journals in 2025. The median journal has an OJR of 0.89, below the world average of 1.00, up 0.03 on 2024; Q1 starts at OJR 1.43. The highest-scoring journal with a stable rank is Science Robotics: its likely rank is within the top 4.
Ranks and citation indicators: 2025. Journal access status and listed APC: source snapshot September 23, 2026.
Journals whose main subfield sits in this category and that published at least 30 citable documents (articles, reviews and conference papers) in 2022–2024, the window the 2025 score is computed on.
The OpenJournalRank Indicator (OJR) is a free, publicly available metric of a journal’s field-normalized citation impact, computed from open OpenAlex citation data. It compares citations to a journal’s papers from the previous three years with the world average for papers of the same subfield, year and type, so 1.00 is the world average and values can be compared across fields. It is computed with the NCI3 method.
The middle OJR among ranked journals in this category: half score higher, half lower. 1.00 is the world average for papers of the same subfield, year and type.
The dot is this category, the solid tick is the median of all ranked journals and the dashed line is the world average.
Share of ranked journals in this category that are fully open access, so every paper is free to read. Hybrid journals, which sell subscriptions and open single papers for a fee, are not counted.
Median list price of the article processing charge, in US dollars, among ranked journals in this category that list a price above zero. Journals with a listed APC of $0 and journals with no known price are left out of this median. The At a glance table below gives a second median that includes the $0 prices.

Filters
Rank is the position by OJR within the list on screen; 1 is the highest. The small range under it is the likely rank range: in 95% of 1,000 resamples of the journal’s papers, it ranked inside that range. Journals whose ranges overlap are not clearly different. | OJR is field-normalized 3-year citation impact: 1.00 is the world average for papers of the same subfield, year and type, so values compare across fields. The badge is the journal’s quartile in this list. | Citations per paper over a two-year window, counted from OpenAlex. It is not field-normalized, so compare it only between journals of the same field. ▲ or ▼ is the change from 2024. This is OpenJournalRank’s own count, not Clarivate’s Journal Impact Factor. | Citable documents (articles, reviews and conference papers) published in 2022–2024, the window the 2025 OJR is computed on. A journal needs at least 30 to be ranked. | Share of the journal’s 2022–2024 papers that are free to read in any open-access form. The green OA tag next to a title marks a fully open-access journal. | List price of the article processing charge in US dollars. “$0 listed” means the listed price is zero; a dash means no price is listed. | The line is the journal’s OJR from 2016 to 2025. A label compares the 2022→2025 change with the median change of the journal’s field or domain. Rising needs a relative change of +10% or more that is at least 2 standard errors above zero; Falling needs -9.1% or less (rounded), at least 2 standard errors below zero. Sorting uses that relative change. | Compare |

33 Biomedical Engineering journals are labelled rising: their OJR moved up between 2022 and 2025 clearly faster than the median journal of their field or domain.
A journal is rising when its OJR grew from 2022 to 2025 faster than the median journal of its field (or domain, when the field is small), by two tests: the relative change is +10% or more, and it is at least 2 standard errors above zero. So the range of the change at 2 standard errors stays above zero, though not necessarily above +10%.
The bar is that range on a ratio scale; the shaded band, -9.1% to +10%, holds changes too small for a label. The list is ordered by the low end of the range, so the surest rises come first.

The endpoints below each rank show its likely range. How rank ranges are calculated
Citations made in 2025. Corpus-wide, 84.3% of core-journal articles and reviews published that year have at least one matched reference; the share varies by journal and field.
54 additional Biomedical Engineering journals with metrics are unranked under this release’s eligibility rules: a journal needs at least 30 citable documents in 2022–2024, at least 80% of them with a subfield, and a positive world-average expectation. Ranks are within the whole category; filters hide rows without re-ranking. OJR excludes self-citations.

How to read these rankings
- OJR, the OpenJournalRank Indicator
- A field-normalized 3-year citation impact, computed from OpenAlex with the NCI3 method. It divides the citations a journal’s papers received by the world average for papers of the same subfield, year and type, so 1.00 is the world average and 2.00 means twice as many citations as expected. Because it is normalized, it can be compared across fields. Read the methodology
- Quartiles
- Q1 to Q4 split the ranked journals of the list you are viewing into four equal groups by OJR. A journal’s quartile depends on the list: the same journal can be Q1 in its subfield and Q2 among all journals.
- Impact factor (2-year)
- Citations per paper over a two-year window, counted from OpenAlex. It is easy to compare with familiar impact factors but is not field-normalized, so compare it only within a field. It is not Clarivate’s Journal Impact Factor. Why it differs from the Journal Impact Factor
- Rank ranges
- Each rank in the latest year carries a likely range from 1,000 resamples of the journal’s papers. Where two journals’ ranges overlap, the data cannot tell them apart, so treat neighbouring ranks as ties.
