“…Lee et al (Lee et al, 2022) designed novel piezoelectric-triboelectric hybrid nanogenerators (PTHNG) based on MAPbBr 3 (methyammonium lead tribromide) single crystals embedded into porous PVDF (MAPbBr 3 -PVDF), which simultaneously functions as a piezoelectric layer for a piezoelectric nanogenerator and as a dielectric layer for a triboelectric nanogenerator. The power density of the PTHNG is approximately 200 times larger than that of the FIGURE 1 (A) Schematic illustration of the wearable and real-time brain-machine-interface system for enhancing exercise endurance showing the four parts of the system and the electronic circuit of the data processing module (Liang et al, 2022).

A novel self-powered wearable motion sensor for monitoring the spiking gesture of volleyball athletes has been manufactured from piezoelectric PVDF film. The PVDF film can convert body mechanical energy into electricity through the piezoelectric effect, and the flexible device can be conformably attached on the hand or arm. The sensor can work independently without power supply and actively output piezoelectric signals as the sports information. The sensor can detect the tiny and fine motion of spiking movement in playing volleyball, reflecting the skill. Additionally, the sensor can also real-time monitor the pulse changes and language during a volleyball match. The self-powered sensors can link to a wireless transmitter for uploading the sports information and building big sports data. This work can provoke a new direction for real-time sports monitoring and promote the development of big sports data.

Flexible conductive patterns on polyimide substrates are attracting increasing research interest in the areas of wearables, biomedicals, automotives, and energy harvesters. This paper reports a laser-induced selective activation (LISA) process for electroless metallization and, therefore, the creation of complex conductive patterns on polyimide substrates. In this process, a Q-switched pulsed laser is utilized for scanning the surface and forming the catalytic layer consisting of microporous structures, which enhances the stability of electroless plated metallic structures on the polyimide surface and exhibits superior mechanical stability under repeated bending and harsh environments. The high resolution of the metallic patterning enables the demonstration of a copper microgrid pattern with a line width down to 50 μm. Moreover, flexible light-emitting diode displays and electromagnetic interference shielding films are successfully manufactured to indicate the promising capability of our LISA process.
