Novel micropumps have been designed and fabricated. Mercury drops driven by an electromagnetic force sweep the fluid into a pipe. The advantage of these micropumps are their simple structures and lack of moving solid parts. There are two kinds of micropumps, namely, the rotary type and the reciprocating type. Their overall dimensions are 10 mm and 25 mm, respectively. Both types functioned successfull as pumps, and their performance was evaluated using parameters derived from basic experiments. The maximum flow rate, the maximum pressure and the maximum power are 3.4ml min^<-1>, 0.67 kPa and 9.7 μW, respectively for the rotary type, and 0.32 ml min^<-1>, 0.34 kPa and 1.3μW for the reciprocating type. It has been demonstrated that a restoring force caused by surface tension can be errectively used in the microscale. This paper presents a method of calculating the restoring force based on appropriate assumptions.
