“…A measured type of strain can either be torsion, axial, bending or pressure as the elongation level of graphene film or polymer/graphene composite will lead to the variation of strain magnitude. A wide spectrum of potential applications of graphene-based strain sensor have been reported, including pulse sensing [ 1 , 89 ], human body range detection [ 90 ] and words classification [ 91 ]. During the pandemic, constant monitoring of heartbeat is crucial as the breathing difficulty, which is one of the major symptoms for Covid-19 may affect the heartbeat rate person.…”

Flexible sensor technologies have gained extensive interest in recent yearsowing to the increasing demands of wearable electronics. Here, the authors propose a flexible strain sensor with enhanced sensitivity by designing a new sensing approach for strain detection. The sensing approach uses an over-balanced planar elastomer (OBPE) inspired by Kirigami-like auxetic structure for stretchable sensing. The OBPE substrate is designed and fabricated with four polydimethylsiloxane (PDMS) supporting beam embedded into Ecoflex elastomer to realize auxetic characteristics. The auxetic characteristics induce the sensing region of the sensor to expand in directions both along and orthogonally to the stretch loading. Consequently, the local disconnections of the electrically linked paths composed of multi-wall carbon nanotubes (MWCNTs) in the sensing region are enhanced. Gauge factor of the OBPE strain sensor is improved up to 6 times higher than the typical strain sensor without OBPE architecture. Therefore, the enhanced sensor outputs the stronger electrical signals than the typical sensor in perceiving human motions. Moreover, the two-step casting fabrication is a low-cost process and suitable for large volume manufacturing. In addition, as this sensing method is independent of the constituent conductive materials, it has the potential to be further employed for developing other stretchable strain sensors.

“…Flexible strain sensors are mainly composed of flexible substrates and conductive functional materials. , Flexible substrate materials, including polyethylene glycol terephthalate (PET), thermoplastic polyurethanes (TPU), polydimethylsiloxane (PDMS), polyimide (PI), polypropylene (PP), and other polymer materials, provide reasonable support and protection for the conductive functional materials. Furthermore, common conductive nanomaterials include graphene, carbon nanotubes, metal nanoparticles, and inorganic semiconductor materials, etc.…”

Flexible strain sensors have attracted extensive attention due to their promising applications in wearable electronics and artificial intelligence, and VO 2 smart materials have been applied in this field due to their sole stimuli-response. In addition, the direct writing method is very facile for the preparation of flexible sensors. Herein, the VO 2 (B) nanobelts with the width ranging from 100 to 200 nm were synthesized by the hydrothermal method in this work. Subsequently, VO 2 (B)-based flexible sensors were prepared via the direct-writing strategy, where the conductive ink containing synthesized VO 2 (B) powders was patterned on the different substrates by pen or brush. The sensors exhibited high sensitivity (GF = 470) and excellent stability (stretch−release cycles more than 1000) and can accurately monitor varieties of human health signals (respiration, pulse, muscle state, etc.). As-prepared smart integrated glove associating with LEDs and power supply can effectively achieve gesture recognition and a primary human−computer interaction model. Furthermore, the sensing signals of joint movements were collected by VO 2 (B)-based flexible sensors and then remotely transmitted to the smart terminal through a wireless local-area network, which achieved real-time monitoring of human movement. Therefore, this work demonstrated the potential application of a VO 2 (B)-based conductive ink in wearable electronic devices and human−computer interaction systems.
