Medical Micro-Electro Mechanical Systems (MEMS) Can Be Used In Drug Delivery
Medical Micro-Electro Mechanical Systems (MEMS) |
In a world where microchips containing sensors, actuators, circuitry and memory have become commonplace, MEMS, Medical Micro-electro Mechanical Systems (MEMS) are entering the realm of the biomedical industry with great promise for improving the quality of medical care. MEMS devices can sense pressure, detect movement and forces, identify chemicals and other bio-agents, pump fluids and perform many other functions that can be of value in medical and biological applications.
Medical Micro-electro Mechanical
Systems (MEMS)
can be fabricated using a variety of
materials, including silicon, alumina, glass, teflon, and borosilicate glass,
ceramics such as lead zirconate titanate, barium strontium titanate, and
aluminum nitride, and metals such as titanium, gold, silver, copper, nickel,
and iron. MEMS can be fabricated in very small volumes with great uniformity
and reliability, comparable to integrated circuits.
The Global Medical Micro-Electro Mechanical Systems (MEMS) Market Is Expected To Be Valued At US$ 4,710.4 Million
In 2019 And Is Expected To Exhibit A CAGR Of 18.5% Over The Forecast Period
(2019-2027).
The most promising applications of Medical Micro-electro Mechanical Systems
(MEMS) in medicine are related to drug delivery and sensor-based monitoring
systems. In the case of drug delivery, MEMS can address a number of problems
associated with conventional drug administration such as long-term treatments,
narrow therapeutic windows, complicated dosing schedules, combined therapies,
and labile active substance administration. Implantable MEMS devices may be
designed for controlled release of drugs without the need to create an
incision, thereby avoiding complications associated with conventional
intravenous and intramuscular injections.
Medical
Micro-electro Mechanical Systems (MEMS)drug
delivery systems typically consist of a micropump and one or more
drug-containing reservoirs. The drug is stored in the microreservoirs and then
released into a patient's blood stream over time or at specific intervals
through porous membranes. These MEMS drug release devices avoid the need for
invasive infusion procedures and can be actuated by both external and internal
stimuli, which can be mechanical or electrical.
Similarly, Medical Micro-electro Mechanical Systems (MEMS)can be used to
develop medical stents that are deployed within a patient's body to keep a
vessel open. A capacitive Si pressure sensor can be integrated into a stent to
monitor the pressure in a blood vessel continuously. This type of system can
detect recrudescence, and the detected signals can be transmitted outside the
body for diagnosis.
Another example of a Medical Micro-electro Mechanical Systems
(MEMS) sensor-based system is a brain probe that can be inserted into a
patient's skull to stimulate the brain physically or chemically. Such probes
are expected to allow for more accurate diagnoses and treatment of neurological
disorders, especially in patients with cognitive impairments.
