Key Technologies Behind MEMS- Based Drug Delivery

Several MEMS- enabled platforms are currently in development or already on the market.

Implantable Micro-Pumps

Implantable drug pumps have been used for decades, but MEMS technology has made them much slaller and more relieble. Modern MEMS micro- pumps use piezoelectric or electrostatic actuation to move fluid through micro- channels. These pumps can deliver drugs at rates aw a los nanoliters per hour, which is essential for potent medicions like es or anesthetics.

Smart Pills andd Capsules

Ingestible MEMS sensors are transforming diagnostics andd premed gastroequity inal delivery. For example, the PillCam color capsule uses a MEMS camera and pressure sensor to nawigate thee color. Expanding this concept, research chers at MIT have developed a smart capsule that senses pH and temperatur changes to release drugs in specific sections of thee estile. This could improwime treatments for Crohn 's disease or color cancear.

Mikroneedle Arrays

Mikroneedle made from silicon, metal, or biocompatible polimers can e coated with a drug formulation. When pressed into the skin, thee needle disolve or release the drug. Integrating MEMS strain gauges or capacitititiva sensors allows the device to metriure skin resistance and ensure consistent intration depth. Thi combination of sensing and drug delive ides ideal for vaccines that require precise intradermal administration.
