Glass-Based Biodegradable Pressure Sensor toward Biomechanical Monitoring with a Controllable Lifetime
A New Class of Potentially Implantable Solid-State Sensors is Demonstrated Utilizing Biodegradable Glass as the Main Structural Material. the Device Behavior is Manipulated Via Chemical Decomposition, and Then Physically Disintegrated in a Controlled Manner. It is based on the Capacitive Sensing Mechanism, Comprising an Elastic Insulator between Two Borate-Rich Glass Substrates. This Mesoscale Pressure Sensor is Characterized by a Range of Pressure of Up to 14 MPa in a Phosphate Buffer Solution Environment. the Sensor Exhibits Good Sensitivity and Reversibility Responding to Compressive Pressures and Remains Fully Functional Before a Desired, Sudden Failure Caused by Dissolution. the Operational Lifetime Can Be Modified by Altering the Chemical Composition or Thickness of the Biodegradable Glass Component. the Proposed Device Concept is a Viable Option toward Various Temporary Implantable Devices Without Needing an Additional Surgical Procedure to Remove Them after their Duty.
