“…A potassium-selective electrode was fabricated with cellulose hydrogel as internal electrolyte, which contained 2 wt % hydroxyethyl cellulose (HEC) and 21 wt % triethylene glycol dissolved in 0.1 M KCl. After casting the hydrogel layer, the ion-selective membrane solution, which was prepared according to [3] was drop casted inside the reservoir on top of the hydrogel layer. The ion-selective membrane solution casting was repeated three times till an optimal thickness of the membrane was achieved.…”

“…We introduced an earlier prototype of the miniaturized ion sensors with an integrated hydrogel polyhydroxyethylmethacrylate (pHEMA) based RE for potassium and sodium sensing [3]. In these sensors, the hydrogel pHEMA was both used as the internal electrolyte for the reference electrode and for the ion-selective electrodes.…”

This work presents a flexible miniaturized ion-selective sensor consisting of a solidcontact reference electrode (RE) and ion-selective electrodes (ISE) fabricated on the same foil. The flexible ion sensor was based on AgCl electrodes screen printed on polyethylene terephthalate foil. The RE was formed by casting a mixture of plasticized polyvinylchloride (PVC) and KCl on the AgCl electrode. The ISE consisted of a stack of AgCl electrode, cellulose gel layer loaded with 0.1 M KCl, and plasticized PVC based ion-selective membrane containing ionophores. The flexible ion sensor showed a sensitivity close to the Nernstian value in a biological relevant range.

“…In aging highly-technological societies, there is an increasing demand for health monitoring resulting in increase of both quality of life and life expectancy. People traditionally visit hospitals for frequent medical examinations; however, this is expensive and does not prevent sudden or chronic diseases (such as, arrhythmia, vitamin deficiency, abnormal blood bacteria, [79][80][81] cholesterol, [82,83] cortisol, [84][85][86][87] dopamine, [88,89] glucose, [90][91][92][93][94] glutamate, [95] ions, [96][97][98][99] lactic acid, [100][101][102] protein, [103][104][105][106] uric acid, [107][108][109][110] and viruses.

The limited effectiveness of medical examinations has triggered the demand for 24-h monitoring technology. Wearable healthcare sensors are a promising option because they are small, light, wireless, and biocompatible with the human body. [8][9][10][11][12][13][14][15] Moreover, as they can potentially be organized in clouds, they can easily be combined with artificial intelligence (AI) to realize inexpensive intelligent systems for disease diagnosis and prevention. [16,17] Figure 1 shows that wearable healthcare sensors are classified in two categories: physical and chemical. Physical sensors include strain, temperature, touch and tactile, and pressure sensors. Wearable strain sensors are primarily used to monitor motion, breathing frequency, and pulse. [34] They should be able to sustain large deformation to accommodate the substrate, while at the same time they should have a high gauge factor to ensure highprecision recognition of small strains. Temperature sensors can both monitor the body temperatures of people with fever and monitor anesthetized people, predict ovulation times, and evaluate wound/postoperative recovery. [35,36] Touch and tactile sensors are then used as an artificial skin to help disabled persons with tactile sensations. [37][38][39][40][41] Wearable pressure sensors are extensively used in professional sports to enhance athletic ability and monitor health. [42][43][44] In the healthcare, pressure sensors detect small perpendicular deformations triggered by pulse and voice. [45][46][47] Physical sensors can be combined with prostheses to achieve multiple functions and help disabled people with missing limbs.Chemical sensors are used for health monitoring and detecting important organic-inorganic molecules serving as potential disease indicators. The human body performs multiple functions via biochemical reactions based on inorganic and organic materials. The concentration stability of organicinorganic molecules, such as bacteria, viruses, and uric acid, is important for health. [48][49][50] For example, a reduction in skin hydration level can lead to eczema, acne, itching, and even cracking of the stratum corneum, which makes people suffer and look older. [51] Chemical sensors can be used to monitor health by detecting important organic or inorganic molecules and their reactions. Existing chemical sensors detect potential disease based on certain indicators, such as humidity, [23,[52][53][54][55][56][57][58] hydration, [59][60][61][62][63] transcutaneous oxygen, [7,[64][65][66][67][68] vitamin A/B/C/D, [3,4,[69][70][71][72][73] hydrogen peroxide, [74][75][76][77][78] arrhythmia, [1,2] Large healthcare markets have been created in highly developed economies to improve the quality of life. Wearable healthcare sensors are attracting considerable interest because of their 24 h real-time monitoring capability, which make them useful in the detection of potential diseases. To guide the diagnosis, these sensors are designed to monitor various physical (e.g., pressure, temperature, strain, touch, bi...
