Biodegradable capacitive pressure sensor toward temporary implants for intervertebral pressure monitoring
Keywords and Phrases
Biodegradable; Pressure sensor
"The objective of this thesis is to demonstrate a new class of implantable biomedical device, based on biodegradable borate glass as the substrate material that can be potentially used to monitor the intervertebral pressure in the lumbar region of the human body. Two major types of implantable biomedical devices include the permanent prosthetic devices such as pacemakers and the temporary implants for short-term intervention and monitoring. Unless surgically removed after their intended operation, the temporary implants are left inside the body causing electromagnetic issues, latent complications and various biomechanical safety concerns. In order to address this issue, a new device concept is developed that can be biodegraded inside the body without producing any adverse effects after their operational lifetime.
A series of studies are conducted to design and fabricate a biodegradable capacitive pressure sensor towards intervertebral pressure monitoring. The device is characterized over a wide range of pressure in a phosphate buffer solution environment. The capacitive sensor responds to compressive pressure and remains fully functional for a desired lifetime before it is dissolved, thereby validating the proof-of-concept of a biodegradable device. Borate-based biodegradable glass material is successfully used as a novel functional platform to fabricate solid state sensors towards temporary implantation"--Abstract, page iii.
