In a recent article, we looked at how piezo motors are used in liquid handling robots for contact-based dispensing (also referred to as pipetting) of microliter and nanoliter volumes. But when the required dispense volumes fall in the single-digit nanoliter or picoliter range, the process often requires a non-contact dispensing method to ensure accuracy and […]

Piezo motors and actuators are used in a variety of medical applications, including liquid handling robots for laboratory testing and diagnostics, drug discovery, and biotechnology.  Liquid handling functions in the medical industry have traditionally been done manually by laboratory personnel. But consistency and accuracy are difficult to ensure with manual methods, since variations between technicians […]

More and more, medical device manufacturers are replacing traditional components with smaller, lighter-weight options that have sufficient life and reliability for “life-critical” applications. One such example comes from manufacturers of ventilators, who are using voice coil actuators to control the valves that deliver air to a patient who’s unable to breathe on their own. Ventilators are […]
