Gizmoz and Gadgets: Biomedical Gadgets

Biomedical What is biomedical? �Biomedical engineering or medical engineering is the application of engineering principles and design concepts to medicine and biology for healthcare purposes

Biomedical Gadgets �Biomedical engineering is a field that focuses on creating technologies that help people when they are sick or hurt. � Biomedical engineering use math and science skills to develop things such as artificial limbs, dentures, blood testing machines, physical therapy equipment, x-rays and more.

Biomedical Engineering �Biomedical engineers make medical devices to improve human healthcare.

Examples �Mixture of engineering, mainly mechanical, and biology. �A robotic hand is a great example of Biomedical engineering. Who would need it ?

Engineering Process

Robotic Hand Structure �What happens when you close your hand to a fist? �Where does your hand bend?

Robotic Hand: Structure �The robotic hand will be required to bend like a really hand.

Robotic Hand: Force �The robotic hand will have to be gentle picking up the egg or else there will be a big mess.

Robotic arm activity �Grip strength test in lab. Grip test at home

Blood pressure monitor �The most common and old bio gadget is blood pressure monitor �Blood pressure is usually expressed in terms of the systolic pressure (maximum during one heartbeat) over diastolic pressure (minimum in between two heartbeats)

Robotic Hand: Control �Muscles move on commands from the brain. �Single nerve cells in the spinal cord, called motor neurons, are the only way the brain connects to muscles.

Robotic Hand: Control �Muscles move on commands from the brain. �When a motor neuron inside the spinal cord fires, an impulse goes out from it to the muscles on a long, very thin extension of that single cell called an axon.

Robotic Hand: Control

Robotic Hand: Attachment

Other Examples �Another example is a robotic arm. �Where does an arm bend?

Other Examples �Other examples include robotic legs. �Where does a leg bend?

Wearable bio Gadgets �The most common wearable biomedical gadget is smart watch or bands �Monitor heart rate �Activities �sleeping

Wearable bio Gadgets �There are biosensors for athletes to monitor and improve their sports abilities. �It track steps and the foot placement of runners. smart socks

Brainwaves EEG sensors

Bio Gadgets: Type I Diabetes �Body cannot produce insulin �Solution ? �Customized/engineered beta cells can produce insulin �Immune system thinks those beta cells are foreign �Surround beta cells with hydrogel �Material that immune system won’t kill �Knowledge of how different materials interact with the body

Designing and Printing 3 D Organs

Defibrillator

Pacemaker A pacemaker is a small device that's placed under the skin in your chest to help control your heartbeat

Chronic Pain �Use devices to interrupt (add interference ) to a pain signal as it travels to the person’s brain �Replace the pain feeling or greatly reduce it

Deep Brain Stimulation �Parkinson �Epilepsy �Depression/Mood regulation

Future bio gadgets �A designed tattoo that will not only collect your health information but also send it to your doctor for consultation. �Your doctor will know if you are not feeling well even when you don’t know yourself. Tech Tattoos
