生物医学工程处于工程学，生命科学和医疗保健的交汇处。生物医学工程师从应用科学（包括机械，电气，化学和计算机工程）和物理科学（包括物理，化学和数学）中汲取原理，并将其应用于生物学和医学。尽管人体是比最复杂的机器更复杂的系统，但构建和编程机器的许多相同概念也可以应用于生物结构以及诊断和治疗工具。目标是更好地了解，更换或修复目标系统，以最终改善医疗质量。<br> <br>生物医学工程师参与了研究与开发，涉及广泛的子领域：生物力学，生物材料，组织工程，神经工程，医疗设备，临床工程，医学影像。突出的生物医学工程应用
Biomedical engineering is at the intersection of engineering, the life sciences and healthcare. Biomedical engineers take principles from applied science (including mechanical, electrical, chemical and computer engineering) and physical sciences (including physics, chemistry and mathematics) and apply them to biology and medicine. Although the human body is a more complex system than even the most sophisticated machine, many of the same concepts that go into building and programming a machine can be applied to biological structures and diagnostic and therapeutic tools. The goal is to better understand, replace or fix a target system to ultimately improve the quality of healthcare.<br><br>Biomedical engineers become involved in research and development, spanning a broad array of subfields: biomechanics, biomaterials, tissue engineering, neural engineering, medical devices, clinical engineering, medical imaging. Prominent biomedical engineering applications include the development of biocompatible prostheses, various diagnostic and therapeutic medical devices ranging from clinical equipment to micro-implants, advanced imaging methods such as MRIs and EEGs as well as development of regenerative tissue and artificial organs.<br><br>Biomedical engineering is the fastest-growing career and this trend is expected to continue over the next decade. Ireland's medical technology sector has evolved into a global leader for medical device and diagnostic products, with exports annually exceeding €12bn. Ireland has over 450 companies involved in developing, manufacturing and marketing medical devices. These include Abbott, Bayer, Becton Dickinson, Boston Scientific, Johnson and Johnson, Guidant, Medtronic and Stryker. These companies have a strong demand for high quality graduates at the Masters and PhD level because of the high technical level of their products. Biomedical engineers also find employment in clinics and hospitals where they work as clinical engineers, responsible for complex, expensive diagnostic equipment and laboratories.
