“…16a and b). 21 Using both catalytic (CoPc@C fix-bedded) and optical (LED light irradiation) triggers for the back reaction, this system generated power continuously for almost 30 minutes (see Fig. 16c and d), demonstrating for the first time that MOST technology can transfer solar energy into electricity beyond time and geographical restrictions, and can thus be used as a new type of carbon-based heavy metal free solar battery.…”

“…Since some of these heat sources are often limited by time and geography, they could be stored and released on demand to the thermoelectric converter to achieve power generation independent of time and space. 1 Natural or artificial radioisotopes that release heat can also provide heat sources for thermoelectric converters to develop radioisotope thermoelectric generators of different powers to power devices ranging from pacemakers to satellites. Thermoelectric converters can also utilize the heat of living organisms to generate electricity for low-power microelectronic devices.…”

“…Electricity is an essential commodity in modern society and more than 85% of the world's electricity supply comes from the combustion of primary fossil fuels such as coal, oil, and natural gas. 1 Such large-scale high-temperature combustion power generation technology inevitably brings environmental pollution and releases huge greenhouse gases. As the United Nations' Intergovernmental Panel on Climate Change (IPCC) has warned, the average global temperature rose by 1 °C between the Industrial Revolution and 2018 and could reach 1.5 °C as early as 2030.…”

As heat engines, thermoelectric converters can utilize a large amount of free low-grade thermal energy in the environment to generate electricity cleanly and quietly, contributing to a sustainable low-carbon life. They can also act as refrigerators and sensors based on their special ability to reversibly convert heat to electricity. Attractively, thermoelectric converters fabricated by microelectromechanical system technology exhibit more powerful potential when reaching the micro/nano-scale owing to the characteristics of electrons and phonons transport, with cost-effective mass manufacturing advantages. Thermoelectric converters will play an increasingly important role in extensive fields with a bright future.

Inherent in humans is the capacity to perceive music and art, engaging both the visual and auditory senses, with profound effects on physiological and psychological states. Sound and light possess the remarkable ability to transform into thermal energy and, ultimately, electrical signals, playing a crucial role in human sensory perception. This research introduces a previously unmentioned synesthesia‐inspired image and sound recognition system, diverging from conventional image/sound acquisition techniques based on photo/mechanical‐electrical conversion. Leveraging the photo/acoustic‐thermal‐electric effects, the system utilizes micro‐/commercial thermoelectric devices as a conduit for energy conversion. It successfully discriminates monochromatic red, green, blue (RGB) and color coverage, showcasing its proficiency in distinguishing ten digital paintings. Additionally, by probing fiber responses to varied sound frequencies and loudness levels, the system achieves time‐domain identification of four classical music compositions. The device exhibits high sensitivity to detecting input energy and its inputting rate power, offering a novel approach to image and sound recognition through thermal signals. Potential applications span from bionic image sensors and time‐domain thermal monitoring of audio. With further exploration, this thermoelectric‐based system holds promise in quantifying emotional responses to images and sound.
