丹麥Unisense 
丹麥Unisense公司是世界上微電極制造領域的頂級專家，成立于1998年.Unisense制造的微電極精度高、壽命長，非常適合科學研究和在線監測。

Unisense公司目前推出的微電極有氧微電極、硫化氫微電極、氫氣微電極、氧化亞氮微電極、一氧化氮微電極、pH微電極、氧化還原電位微電極、微流速電極。在微電極的基礎上，Unisense公司開發了微呼吸儀、超微呼吸儀、胚胎呼吸生長分析儀、水沉積物界面分析儀。

微電極是一類空間精度和測量精度非常高的電極，其尖端外徑從幾微米至幾百微米不等，它與普通毫米級的電極相比具有獨特的電化學性能即無擾動地測量微環境中的理化參數，不破壞被測點的微生態環境。它可以對沉積物、生物膜、河流底泥、污泥絮體、植物根際、擴散邊界層、菌落、植物或動物組織等進行微米穿刺測量濃度梯度并能進行實時在線原位監測,從而能深入解析反應過程機理,提煉出數學模型為過程的優化創造條件。微電極也適合放進生物培養器中進行實時在線分析。

微呼吸儀能分析水體、藻類、魚卵、小動物、線粒體的呼吸作用，能夠從呼吸的角度進行生理和毒理研究。超微呼吸儀能夠分析特別微小的卵的呼吸作用。胚胎/受精卵分析儀能實時測量和拍攝受精卵從第一次分裂開始時的呼吸和生長發育情況，適合做高質量的胚胎篩選研究和生理研究。

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.
