丹麦Unisense 
丹麦Unisense公司是世界上微电极制造领域的顶级专家，成立于1998年.Unisense制造的微电极精度高、寿命长，非常适合科学研究和在线监测。

Unisense公司目前推出的微电极有氧微电极、硫化氢微电极、氢气微电极、氧化亚氮微电极、一氧化氮微电极、pH微电极、氧化还原电位微电极、微流速电极。在微电极的基础上，Unisense公司开发了微呼吸仪、超微呼吸仪、胚胎呼吸生长分析仪、水沉积物界面分析仪。

微电极是一类空间精度和测量精度非常高的电极，其尖端外径从几微米至几百微米不等，它与普通毫米级的电极相比具有独特的电化学性能即无扰动地测量微环境中的理化参数，不破坏被测点的微生态环境。它可以对沉积物、生物膜、河流底泥、污泥絮体、植物根际、扩散边界层、菌落、植物或动物组织等进行微米穿刺测量浓度梯度并能进行实时在线原位监测,从而能深入解析反应过程机理,提炼出数学模型为过程的优化创造条件。微电极也适合放进生物培养器中进行实时在线分析。

微呼吸仪能分析水体、藻类、鱼卵、小动物、线粒体的呼吸作用，能够从呼吸的角度进行生理和毒理研究。超微呼吸仪能够分析特别微小的卵的呼吸作用。胚胎/受精卵分析仪能实时测量和拍摄受精卵从第一次分裂开始时的呼吸和生长发育情况，适合做高质量的胚胎筛选研究和生理研究。

Unisense A/S was established in 1998 by a team of university scientists with more than 20 years of experience in developing, constructing, and applying microsensors.

From 1993-1998, seven researchers from the Department of Biology at the University of Aarhus in Denmark received approximately 1.5 million Euro for research and technological development, primarily from the 4th European Frame Program of the European Commission. During this period, a series of innovative sensors and measuring principles were developed, three of which were subsequently patented internationally. In keeping with the demands of The European Commission to exploit the new developments commercially, the company Unisense was founded in 1998.

The company grew and now encompasses the production of sensors and measuring equipment as well as specialized development of measuring principles for a wide range of applications, serving scientists worldwide.

Some of this development led to the founding of a subsidiary company, Unisense FertiliTech, in 2003. The activities of this company are focused in the rapidly growing medical market and are based on two international patents pending on sensors for blood perfusion and devices to improve in vitro fertilization.

In 2005, in order to serve our widely branching groups of customers and interests, Unisense was divided into three branches: Unisense Science, Unisense FertiliTech , and Unisense Medical.
