Low-cost Ventilator

The procurement and maintenance cost of high‐end ventilators preclude their stockpiles sufficient for the mass emergency situations. Therefore, there is a significant demand for mechanical ventilators in such situations. Herein, a low‐cost, portable, yet high‐performance design for a volume‐controlled mechanical ventilator is proposed. Pneumatic artificial muscles, such as air cylinders, are used in the inverseContinue reading “Low-cost Ventilator”

Soft Robotics

Pneumatic actuators require a source of pressure for operation. This pressure is often provided by bulky and pricey peripherals (compressors, valves, gas tanks, etc.). While working on a different project, through serendipity, I realized my approach could address the mentioned challenge associated with pneumatic actuators! We reduced the cost of the device from >$1000 toContinue reading “Soft Robotics”

Fiber Actuators/Artificial Muscles

Also known as muscle-like actuators are devices/materials that can expand/shrink in length, bend, or rotate in response to an external stimulus such as heat, electric field, magnetic field, light, fluid pressure, redox reactions, etc. I have worked on the following types of artificial muscles at a system level and also device level. Thermal actuators: As theContinue reading “Fiber Actuators/Artificial Muscles”
