BACKGROUND Small-scale micro-bioreactors have become the cultivation vessel of choice during the first steps of bioprocess development. They combine high cultivation throughput with enhanced cost efficiency per cultivation. To gain the most possible information in the early phases of process development, online monitoring of important process parameters is(More)
A time of flight sensor has been equipped with a sensing wire parallel to the flow direction (flow parallel wire, FPW). A heat pulse is generated with a coil in the flow channel. The FPW has a center tap allowing its upstream and downstream parts to join in a half bridge. When a heat pulse passes the FPW, a large output peak is generated. The time between(More)
A bistable microvalve is presented in this paper. The microvalve is fabricated using a cheap and developing technology combined of micro-milling of a polymer, sputtering, photolithography and adhesive bonding. The bistable characteristic of a magnetic system compensates the high power consumption of thermopneumatic actuators. The initial gap height between(More)
