“…The WPU/G-ink/CF exhibits high stability and durability upon repeated cyclic heating and cooling actions under the applied voltages of 3 and 7 V (Figure d), affording almost the same curve for the change in resistance after 50 cycles, which is indicative of its feasibility as a flexible wearable heater. During the past few years, great achievements had been obtained in the electrothermal responding temperature of fabric heaters in the range of 36–162.1 °C under an applied voltage of 3–30 V. − To the low-voltage-activating electrothermal response, the heater of WPU/G-ink/CFs shows the highest steady-state temperature of 328.3 °C at a low voltage of 9 V (Table S2). In addition, the heaters have remarkable washability, cyclic stability, and environmental resistance properties.…”

Wearable conductive fabrics are an essential part of flexible electronics, which can be used as portable devices for human thermal management, healthcare, and motion detection. However, obtaining low-cost and scalable production of these types of conductive fabrics with high conductivity, low-voltage-activating electrothermal response, and satisfactory washability still has critical challenges. Herein, high-conductive graphene ink-decorated cotton fabrics (CFs) are fabricated via a facial double-side screen-printing technique for flexible wearable heaters and strain sensors. The porous and rough CFs with spatially distributed graphene inks create efficient pathways for electron movement, and the outmost water-soluble polyurethane could dramatically promote the washability, cycling stability, and environmental resistance properties of conductive fabrics. Interestingly, the as-obtained graphene conductive textiles demonstrate high conductivity (1.18 × 104 S/m), which are applied to flexible wearable heaters, showcasing a high steady-state temperature (52.6 °C) at a low voltage of 3 V, excellent washability, cycling stability, and environmental resistance properties. Additionally, the fabricated conductive fabrics can also be applied to wearable strain sensors, which exhibit high sensitivity, excellent recovery, and stability in a refined strain range for responding to human motions. Consequently, the designed graphene conductive fabrics provide a promising strategy to realize low-cost and scalable next-generation wearable electronic textiles.

“…The high-intensity peak at 1559 cm À1 is attributed to the symmetric stretching of the aromatic C]C ring, the peak at 1345 cm À1 is related to the ring-stretching mode of PPy, the peak at 1053 cm À1 is attributed to C-H inplane deformation, and the peak at 940 cm À1 corresponds to the C]C backbone stretching, indicating the successful polymerization of PPy. [48][49][50] In addition to that, it can be seen that there are three distinct peaks at 471, 512 and 674.5 cm À1 , which are caused by Co 9 S 8 .

“…[204] Generally, charged drugs are loaded into electroactive materials by electrochemical methods, where anion and cation drugs can be released through reduction-negative or oxidation-positive potentials. [205,206] Among all conductive conjugated polymers, PPy, [207,208] PEDOT, [209][210][211] and PANI [212,213] are the most widely studied. [214] Ensuring adequate power supply of IWMDs to provide sufficient charge to support the entire system has always been a challenge.…”

gent wearable medical devices (IWMDs) has advanced rapidly, with research emphasis on physiological/pathological factors inducing biosensing and active delivery of therapeutic agents in an ondemand manner. [1] IWMDs constitute a vast array of wearable types, such as wrist bands, smart contact lenses, smart patches, and electronic textiles, which are used to measure biophysical or biochemical signals and, most recently, to achieve therapeutic interference by establishing microenvironmental detection-delivery feedback cycles. Accordingly, IWMDs have become critical components in achieving personalized healthcare and precision medicine. [2] Such devices can provide predictive bio-analysis and offer timely treatment intervention, improving drug efficacy, overcoming the potential dangers due to delayed treatment, and expanding the flexibility of drug use in time and space.For biodetection and monitoring, wearable biosensing devices (WBDs) have been developed to detect many physiological features such as mechanical deformations, electrocardiogram (ECG) signals, body temperature, [3][4][5] and biochemical components such as glucose, calcium ions, and lactate. [6][7][8] For a long time, efforts have been made to advance WBDs by tracking single analytes to multiple analytes. Previous reviews have described several types of representative wearable sensors for healthcare monitoring. [9] For drug delivery, transdermal/topical wearable delivery devices (WDDs) are advantageous over oral and injection delivery modalities in terms of flexibility and scalability and have been utilized to deliver therapeutic agents such as polypeptides, [10][11][12] polysaccharides, [13] small molecules, [14] and growth factors [15] continuously and responsively. Recent studies indicate that wearable transdermal patches constructed from responsive materials show great advantages and attractive prospects in application of WDDs. [16] Despite the considerable development of WBDs and WDDs, efforts are being made to combine them into a single system to provide both sensing and delivery services, for which IWMDs are expected to realize two core functions: identification of physiological/pathological markers and delivery of therapeutic agents. [17] As Figure 1 shows, IWMDs are defined as composite pieces of equipment that contain multiple subsystems, including embedded sensors, drug repositories, and their connecting attachments. In addition, some other components, The primary roles of precision medicine are to perform real-time examination, administer on-demand medication, and apply instruments continuously. However, most current therapeutic systems implement these processes separately, leading to treatment interruption and limited recovery in patients. Personalized healthcare and smart medical treatment have greatly promoted research on and development of biosensing and drug-delivery integrated systems, with intelligent wearable medical devices (IWMDs) as typical systems, which have received increasing attention because of their non-invasive and custom...
