Biomedical Engineering

In this lab, students will learn the basic structures and pathway of the digestive system and understand the different functions of the stomach and the small intestine in regards to digestion. They will investigate how the properties of different enteric coatings react in different sections of the digestive system. Next they will explore the purpose of an enteric coating and make a simulated “coating” and engineer a coating most suitable for certain pharmaceutical needs. This lab was written by a Biomedical Engineer and has enough materials for 15 groups. Includes Teacher’s manual and student guide.

Biomaterials to Make Your Own Contact Lenses

Engineers play an integral role in the process of finding a “perfect” material or ratio of materials to maximize the desired properties of an invention and decrease the amount of negative effects of other properties. For example, when developing the perfect material for use in contact lenses, an engineer will have to test many different materials before finding the right one. A hydrogel is a polymer similar to plastic that has favorable optical properties and favorable flexibility/strength but like paper and glasses/ceramics is hydrophilic, which is necessary for a contact lens to function properly. Testing a hydrogel, which is favorable for all three of the main properties needed for a contact lens to function properly, is the main job of a biomedical engineer developing contact lenses today. They make a hydrogel and find the perfect “ratio” of polymer to water. The composition of the hydrogel needs to be hydrophilic enough to maintain a wet environment in the eye but not too hydrophilic so that the contact begins to swell and change size and shape. Students will engineer a lens using 2 different materials. They will determine the correct material and the concentration that has similar properties as a contact lens, while discovering the correct optical properties, tensile strength and hydrophobicity. Kit contains enough materials for 15 groups. Teacher’s Manual and Student Study Guide copymasters are included.

Biomedical engineers design devices, equipment, and processes to improve medical treatment methods and the quality of human health and life. They apply engineering principles to biology and medicine to create products such as prosthetic limbs and artificial organs, among other things. One major focus of biomedical engineers is the design of drug delivery systems, which can control the transport and release of medicine in the body to more effectively treat diseases and illnesses. In this experiment, students will gain an understanding of drug delivery and its importance by testing simulated delivery systems in multiple environments that mimic different parts of the body. The delivery systems will be analyzed and compared, allowing students to engineer an optimal solution and learn what properties must be considered when designing new drug delivery systems. This lab has enough materials for 15 groups. Teacher’s manual and Student Study Guide copy masters included.

Engineer and Explore Materials for Prosthetics

In this lab, students will explore the materials that biomedical engineers use when creating prosthetic devices. They will first investigate the physical properties of various metals, ceramics, and polymers to understand how they differ, and determine which materials would be most suitable for use in a hip replacement prosthetic. Students will then engineer their own prosthetic arm that meets certain design requirements and mimics the functionality of a real hand. Kit contains enough materials for 15 groups. Teacher’s Manual and Student Study Guide copy masters are included.
