ACS340 Biomechatronics

Module Description

There are a wide range of important healthcare challenges in the 21st Century, such as the aging population, stroke, paralysis and the loss of limbs, which can be treated using biomechatronic devices such as exoskeletons, active prosthetic limbs and brain computer interfaces.

‘Biomechatronics’ describes the integration of the human body with engineered devices composed of electronic, mechanical and control components (mechatronics) for the purposes of
(i) emulating and replacing natural human function lost through disease or accident and/or
(ii) augmenting natural human function to generate superhuman abilities.

The biomechatronics module will cover the subject of biomechatronics in theory and practical application, and span the main core topics of: neural control, biomedical signals, sensors and actuators.

Credits: 10 (Spring semester)

Pre-requisites: ACS124, ACS214 or similar

If you have any questions about the module please talk to me during the lectures or the labs in the first instance. It is likely that other students will learn from any questions you ask as well, so don’t be afraid to ask.

Outside of lectures please contact me via email, or drop in to see me.
