Baking Powder Actuated Centrifugo-Pneumatic Valving for Automation of Multi-Step Bioassays
Micromachines, 2016 We report a new flow control method for centrifugal microfluidic systems; CO2 is released from on-board stored baking powder upon contact with an ancillary liquid. The elevated pressure generated drives the sample into a dead-end pneumatic chamber sealed

Linear pneumatic actuator [PDF]
MATEC Web of Conferences, 2017 The paper presents a linear pneumatic actuator with short working stroke. It consists of a pneumatic motor (a simple stroke cylinder or a membrane chamber), two 2/2 pneumatic distributors “all or nothing” electrically commanded for controlling the intake/outtake flow to/from the active chamber of the motor, a position transducer and a microcontroller ...
