Abstract: Solar induced thermal energy is a vital heat source supplementing body heat to realize thermo‐to‐electric energy supply for wearable electronics. Thermo‐electrochemical cells, compared to the widely investigated thermoelectric generators, show greater potential in wearable applications due to the higher voltage output from low‐grade heat and the increased option range of cheap and flexible electrode/electrolyte materials. A wearable photo‐thermo‐electrochemical cell (PTEC) is first fabricated here through the introduction of a polymer‐based flexible photothermal film as a solar‐absorber and hot electrode, followed by a systematic investigation of wearable device design. The as‐prepared PTEC single device shows outstanding output voltage and current density of 15.0 mV and 10.8 A m –2 and 7.1 mV and 8.57 A m –2 , for the device employing p‐type and n‐type gel electrolytes, respectively. Benefiting from the equivalent performance in current density, a series connection containing 18 pairs of p–n PTEC devices is effectively made, which can harvest solar energy and charge supercapacitors to above 250 mV (1 sun solar illumination). Meanwhile, a watch‐strap shaped flexible PTEC (eight p–n pairs) that can be worn on a wrist is fabricated and the realized voltage above 150 mV under light shows the potential for use in wearable applications.

Abstract: Wireless stimulation (WS) technologies have been developed as powerful strategies to modulate cellular behaviour and biological activity remotely and noninvasively through wireless manipulation of electrical signal. These WS systems are constructed from the electrically stimulus-responsive materials (magnetoelectric, piezoelectric, optoelectronic, and bipolar electroactive materials) that are triggered by the primary driving force, general like magnetic field, ultrasound, light, and electric field. With a deeper understanding of the integral role of electrical stimulation played in biological cells, tissues, and organs, WS has become the promising technique to work on neural cell stimulation, for either functional or repair effects, and other biological activities including drug release, electroporation and cancer treatment. This paper summarises existing WS systems in accordance with the utilised stimulus-responsive materials. Also, future directions of WS in potential biomedical applications are discussed. Along with the development of emerging techniques such as bipolar electrochemistry and 3D printing, more effective WS systems will be allowed to apply in biosystems with a change of paradigm.

Abstract: Freestanding flexible electrodes with high areal mass loading are required for the development of flexible high-performance lithium-ion batteries (LIBs). Currently they face the challenge of low mass loading due to the limited concentrations attainable in processable dispersions. Here, we report a simple low-temperature hydrothermal route to fabricate flexible layered molybdenum disulfide (MoS

Abstract: We developed a strip biosensors array based on aptamer-modified gold nanoparticles as receptors and combined the protein-aptamer binding reaction with the streptavidin-biotin interaction as well as the sandwich format. We found that a series of protein receptors obtained a distinct response pattern to each target protein. Three proteins have been well distinguished with the naked eyes and a portable reader without mutual interference, accompanying with lower limit of detection and wider linear range. A complete set of four elementary logic gates (AND, OR, INH, and NAND) and eight combinative logic gates (AND-OR AND-INH OR-INH INH-NAND AND-OR-INH AND-INH-NAND OR-INH-NAND AND-OR-INH-NAND) are thoroughly realized using this array, which could eventually be applicable to the keypad-lock system with enhanced complexity in the near future. Moreover, this array shows excellent linear relationships, anti-interference capability, real human serum s les applicability, long-term storage stability and reproducibility. All indicate that this design has very good prospects for development.

Abstract: Electrochemistry has become a powerful strategy to modulate cellular behavior and biological activity by manipulating electrical signals. Subsequent electrical stimulus-responsive conducting polymers (CPs) have advanced traditional wired electrochemical stimulation (ES) systems and developed wireless cell stimulation systems due to their electroconductivity, biocompatibility, stability, and flexibility. Bipolar electrochemistry (BPE), i.e., wireless electrochemistry, offers an effective pathway to modify wired ES systems into a desirable contactless mode, turning out a potential technique to offer fundamental insights into neural cell stimulation and neural network formation. This review commences with a brief discussion of the BPE technique and also the advantages of a bipolar electrochemical stimulation (BPES) system compared to traditional wired ES systems and other wireless ES systems. Then, the BPES system is elucidated through four aspects: the benefits of BPES, the key factors to establish BPES platforms for cell stimulation, the limits/barriers to overcome for current rigid materials in particular metals-based systems, and a brief overview of the concept proved by CPs-based systems. Furthermore, how to refine the existing BPES system from materials/devices modification that combine CP compositions with 3D fabrication/bioprinting technologies is elaborately discussed as well. Finally, the review ends together with future research directions, picturing the potential of BPES system in biomedical applications.
