Abstract
A micro fluid dispenser including reservoir, glass tube, hollow glass fiber, a piezoelectric element and a controller. The reservoir is to hold fluid to be dispensed. The glass tube has a first end, a second end and a tube body. The first end of the glass tube is connected to the reservoir to receive the fluid. There is a hollow glass fiber for each glass tube. The hollow glass fiber has a first end, a second end and a fiber body. The first end of the hollow glass fiber is connected to the second end of the glass tube to receive the fluid. The second end of the hollow glass fiber has an open tip to act as a nozzle to dispense the fluid. The piezoelectric element forces the fluid out of each of the open tip. The controller controls activation of the piezoelectric element.
