Tactile Sensing Is Becoming the Key Interface for Embodied AI to Enter the Physical World
Release Time：2026-08-10 Reads：37
On August 7, Wang Xingxing, Chairman of Unitree Robotics, stated during an online roadshow that the application of electronic skin is closely tied to the progress of embodied AI foundation models. As these models advance and humanoid robots increasingly integrate into human society, the deployment of electronic skin is expected to accelerate. Embodied intelligence is now moving from prototype validation toward commercial deployment. Furthermore, data from the independent US market research firm IDTechEx indicates that both the number and performance of sensors on future humanoid robots will continue to increase, with the value share of tactile sensing set to grow significantly. The competitive focus in the industry will also shift from laboratory-level sensitivity to reliability, environmental adaptability, system integration, and mass delivery capability.
The Rising Value Weight of Tactile Sensing
As artificial intelligence transitions from the digital world to the physical world, robots must address a more fundamental question beyond “what to see” and “how to move”: when they actually come into contact with objects and humans, can they determine where they are touching, how much force is being applied, and whether the object is slipping, deforming, or becoming unstable?
IDTechEx’s recently released report, Sensors for Humanoid Robots 2027–2037, argues that the humanoid robot industry is moving from concept validation and prototype demonstration to the early deployment phase aimed at commercially scalable machines. The report projects that by 2037, the sensor market for humanoid robots could exceed USD 6.59 billion, with a compound annual growth rate of 21.4%.
Humanoid robots typically need to integrate multiple types of sensors, including environmental perception sensors, force/torque sensors, encoders, inertial measurement units (IMUs), and tactile sensors. Notably, IDTechEx expects that as humanoid robots move toward commercial applications, the number of sensors per unit and their performance requirements will continue to rise for certain sensor categories. According to the report’s sensor cost structure chart, the value share of tactile sensing within the overall embodied AI sensor system is projected to increase rapidly from less than 10% to over 20%.

This reflects an important shift: as robotic tasks expand from moving, transporting, and path planning to precision gripping, flexible assembly, safe collaboration, and complex environment interaction, tactile sensors—capable of directly sensing contact states—will assume increasingly critical functions.
The Industry Is Moving from Early Validation to Commercial Applications
The rising value of tactile sensing also means that the industry is placing higher demands on product capabilities.
In a laboratory setting, a tactile system may complete technical validation as long as it can detect pressure, recognize contact, or output clear data. However, in real world scenarios such as factories, warehouses, commercial services, and homes, robots must cope with continuous operation, repeated loading, bending and impact, temperature and humidity variations, electromagnetic interference, and surfaces of different materials and shapes.
Consequently, commercial customers are no longer concerned only with sensitivity, measurement range, or single response speed. They care about whether the sensor can maintain consistent performance over long term use, whether it can work stably on various curved surfaces and in different packaging structures, whether calibration can be performed quickly, whether faults can be diagnosed when they occur, and whether the supplier can support sustained production expansion and batch delivery.
This means that the competition in tactile sensing will extend from individual sensing elements to flexible packaging, array design, acquisition circuits, signal processing, calibration algorithms, data interfaces, and mass manufacturing capabilities. Being able to complete a prototype validation does not guarantee direct entry into commercial robots; moving from the lab to mass production requires solving a series of engineering challenges—reliability, consistency, system adaptation, and supply chain capability.
AUDIOWELL Has Proactively Built a Full Stack Tactile Sensing Capability
In line with this trend, AUDIOWELL has already established a full stack tactile ecosystem comprising tactile sensors, flexible arrays, data acquisition modules, and analysis software, extending its products to applications such as dexterous hands, humanoid robots, companion robots, and bionic robots.
The product portfolio covers four main categories: single point flexible tactile sensors, which can be attached to complex curved surfaces to perceive local pressure changes; array-type flexible tactile sensors, which use high-density multi-point simultaneous detection to cover areas such as fingertips, palms, soles, torsos, and arms; multi-channel data-acquisition modules with standard communication interfaces; and a professional software platform that supports various pressure visualisation modes—including heatmaps, waveform charts, and 3D graphs—as well as data calibration, filtering, storage, and secondary development.
This combination enables AUDIOWELL to offer tailored solutions for different robot parts: fingertips and palms focus on contact position, pressure distribution, and slip trends; soles focus on pressure centre and terrain changes; torsos and limbs focus on collision detection and safe human-robot interaction. The solution can also be extended to industrial grippers, companion robots, medical healthcare, automotive electronics, and consumer terminals. AUDIOWELL’s long standing capabilities in piezoelectric materials, sensors, actuators, and mass manufacturing also support the extension of tactile systems from “perception” to “feedback”: one end collects contact information, while the other uses piezoelectric actuators to generate controlled vibrations, creating an interactive closed loop of “perception–decision–feedback.”
Enabling Intelligence to Truly Understand “Contact”
As humanoid robots enter the commercial phase, the number of sensors per unit and their performance requirements will continue to increase, and the value weight of tactile sensing within the overall perception system is expected to rise further. Future market competition may not necessarily depend solely on the performance of a single sensing principle, but rather on whether the product can adapt to complex curved surfaces, endure long term repetitive loading, and operate reliably in real-world commercial environments—while delivering stable, calibratable, and controller ready data.
