The sensor is obtained by using bacterial cellulose (BC) as a base biopolymer. BC is then impregnated with ionic liquids. Electrodes are realized by a conducting polymer, within a typical threelayer structure. The sensor performs within a cantilever configuration and produces an open voltage signal as the result of a flexing deformation. A model is proposed for the transduction phenomenon. The composite mechanoelectric transduction capability is exploited for realizing the accelerometer. Benefits of your chemical and transduction characterization with the accelerometer are reported. Lastly, experimental proof in the attainable nature of your transduction phenomenon is offered.Citation: Trigona, C.; Cerruto, S.; Graziani, S.; Di Pasquale, G.; Pollicino, A.

Introduction The pervasive diffusion of electronics has raised the request for lowcost, sensible, smallscale, and miniaturized sensors [1,2]. A big part of each the present and future markets are going to be covered by accelerometers, with quite a few consumable applications in fields such automobiles, cellphones, and wearable electronics, just to mention a few [3]. The interest within this class of sensors is reflected within a number of fabrication processes and operating principles, including resonators and micromachined devices (MOEMS and MEMS) [4]. As a prevalent trend with the adopted technology, the sensor business has proposed integrated accelerometers [8]. Furthermore, accelerometers exploiting optical, resistive, capacitive, and so on., transduction mechanisms have already been proposed [6,7,9]. The price from the sensing program is usually a relevant constraint that will ascertain the accomplishment of technologies, as well as the examples reported above are affected by the require for a power Cefaclor (monohydrate) Epigenetic Reader Domain source. Such a drawback is usually overcome if selfgenerating components [10], which include piezoelectric and aluminum nitride (AlN) [113], are regarded. Even though sensors determined by AlN have raised scientific and industrial interest, micromachined AlNbased devices are based on siliconbased processes [14]. As such, the production of sensors based on this technology cannot be regarded green. Additionally, they will need devoted recycling or disposing processes [15,16]. As a final remark, siliconbased devices are rigid, while flexibility is requested from nextgeneration applications [17]. The need for greener sensing devices, i.e., requiring fewer raw supplies and less energy and limited amounts of nonrenewable matter and generating more effortlessly disposable, recyclable, or even biodegradable devices, imposes the improvement of new technologies according to additional sustainable and greener components. A trend is occur.
