Design, fabrication and assessment of an optomechanical sensor for pressure and vibration detection using flexible glass multilayers

Advanced Functional Membranes for Sensor Technologies

“…The main function of inorganic membranes has been as a support structure, by increasing the sensor surface area, to carry out a capillary action, or as mediators of fluid transport by capillary action. As mentioned in Table 1, glass membranes also are good examples of inorganic membranes that have been reported [38][39][40] for biosensor applications. In this table, more examples of inorganic membranes are given; nevertheless, the reports of organic membranes in sensing applications are much more numerous.…”

“…Aluminum or aluminum oxide [22][23][24][25] Gold [26][27][28] Silver [29][30][31] Titanium oxide [32][33][34] Silicon nitride [35][36][37] Glass membranes [38][39][40] Organic Cellulose nitrate, nitrocellulose, cellulose acetate…”

“…This type of membrane can be of two types; (i) Organic membranes covered by a thin layer of inorganic material, usually, a conductor such as gold [31,[40][41][42][43][44][45]; and (ii) Membranes synthesized by sol-gel methods to obtain structures of inorganic nanoparticles with polymer chains [13,26,30,46]. Finally, composite membranes are multiple layers of membranes that are stacked together side-to-side or vertically to comprise a whole sensor [32][33][34][35][36][37][38]47].…”

Towards a Glass New World: The Role of Ion-Exchange in Modern Technology

“…As happened for electronics, flexibility is also becoming a fundamental paradigm in photonics, favouring the integration of the respective devices in flexible and stretchable substrates and contributing to expand their application scope, from the field of optical interconnections to that of new systems for the continuous monitoring of patient health, or that of implantable devices for minimally invasive medicine, up to the development of a new class of optical sensors and sources [175][176][177][178][179].…”

Flexible Photonic Sensors: Investigation of an Approach Based on Ratiometric Power in Few-Mode Waveguides for Bending Measurement

“…Recent studies have also explored the integration of glass onto polymer structures [10], [11], aligning with the growing focus on flexible photonics based on all-glass substrates and components [12]- [14]. Glass substrates excel for their optical performance, exceptional chemical properties, thermal resilience, and superior refractive index contrast compared to polymer waveguides [13], [14]. The higher elastic moduli exhibited by glass materials, as opposed to plastics and polymers, contribute to their inherent rigidity in a solid state.…”
