About Us


Our mission is to create an innovative drug delivery device platform to accelerate the process of drug discovery and development.

Our Company

MicroMED is a MEMS microchip design house specialising in the development of microinjection devices targeting unmet needs in the most challenging drug delivery applications. MicroMED has established a proprietary high-precision MEMS

drug delivery engine system, capable of delivering broad flow rate from 1 nL/min to 10 mL/min (eight orders of magnitude) with driving force up to 2,000 atm (29,000 psi) of pressure. MicroMED welcomes all types of business connections/

relations in the PDA drug delivery value chain (pharma, biotech, medical injector developer and insurance payer) with the goals below (but not limited to):

• Purchasing of the current micro-engine products

• Co-development of advanced injector products

• Licensing of the micro-engine proprietaries/intellectual properties.


Quality Policy: We are consistently dedicated to providing products and services with the highest quality and regulatory standard to meet and surpass the requirements of safety, effectiveness, and precision treatment for our valuable customers.


MicroMED has established a strong and experienced supply chain for the development of injection devices from raw material suppliers, semiconductor foundries and component providers to contract manufacturers in both the US and Taiwan. These valuable partners have required regulatory certifications and years of experience in supporting medical device design and manufacturing. MicroMED applies its quality management system, providing the necessary structure and controls to help its value-chain supplier team develop products that meet defined safety and performance requirements for high-value drug delivery customers.
