Touchence Inc. - Advancing Tactile Intelligence in Robotics
Company Overview
Touchence Inc. is a specialized deep-tech company based in Tokyo, Japan, that focuses on the development, manufacturing, and sale of high-performance tactile sensors. Established as a venture-backed entity originating from research at the University of Tokyo, specifically within the Ishikawa Senoo Laboratory, Touchence has positioned itself as a critical player in the field of robotics and industrial automation. The companyâ??s core philosophy is to provide robots with a "sense of touch" comparable to human skin, enabling machines to handle delicate objects, collaborate safely with humans, and navigate complex environments with greater precision.
While many robotics companies focus on vision (eyes) and logic (brain), Touchence addresses the missing link in the robotic sensory loop: tactile feedback. Their technology utilizes advanced Micro-Electro-Mechanical Systems (MEMS) and innovative optical sensing techniques to detect minute changes in pressure and displacement across multiple axes.
Core Technology and Innovation
The foundational technology of Touchence revolves around its ability to measure three-axis force (X, Y, and Z directions) in extremely compact form factors. Traditional force sensors are often bulky, rigid, and expensive, making them difficult to integrate into small robotic fingers or flexible surfaces. Touchence overcomes these barriers using:
Optical Displacement Sensing: By using light-emitting and light-receiving elements within a flexible structure, the sensors can measure the deformation of an elastomer layer when it contacts an object. This allows for high sensitivity without the electrical noise issues common in capacitive or resistive sensors.
Multi-Axis Detection: Most tactile sensors only detect vertical pressure. Touchence sensors can detect shear force (sliding movements), which is essential for preventing objects from slipping out of a robotic gripper.
Flexibility and Scalability: The company has developed "skin-like" sensors that can be wrapped around curved surfaces, such as robot arms or humanoid hands.
Product Portfolio
1. ShokacChip Series
The ShokacChip is one of the company's flagship products, marketed as the worldâ??s smallest multi-axis tactile sensor.
* Design: It features a MEMS-based structure that integrates sensing elements into a tiny chip.
* Functionality: It detects three-axis force and can be embedded directly into the fingertips of robotic hands.
* Applications: Precision assembly of electronic components, micro-manipulation in laboratory settings, and integration into consumer electronics where space is a premium.
2. ShokacCube
The ShokacCube is a modular three-axis force sensor designed for easy integration into existing robotic systems.
* Features: It provides high-speed digital output (via I2C or other protocols), allowing for real-time feedback loops in robotic control.
* Usage: It is frequently used in industrial automation to detect the "seating" of a part or to provide force-controlled feedback for grinding and polishing tasks.
3. ShokacSkin
ShokacSkin represents the evolution of tactile sensing from point-based detection to surface-based detection.
* Design: This is a flexible, multi-point tactile sensor sheet. It can be customized in terms of size, number of sensing points (taxels), and shape.
* Functionality: It allows a robot to detect contact anywhere on its "body," not just at the end-effector.
* Safety: This is a critical component for collaborative robots (cobots), enabling them to stop or retract immediately upon contact with a human worker.
4. Custom Tactile Solutions and Evaluation Kits
Touchence provides specialized evaluation kits for researchers and R&D departments. These kits include the sensors, interface boards, and software needed to visualize tactile data immediately. They also offer consulting services to help manufacturers integrate tactile sensing into custom end-effectors for specific industrial use cases.
Primary Services and Applications
Industrial Automation and Logistics
In the manufacturing sector, Touchence sensors enable "force control" in robots. Instead of following a rigid, pre-programmed path, a robot equipped with Touchence sensors can "feel" its way through a task. For example, if a part is slightly misaligned, the robot detects the resistance and adjusts its position dynamically. In logistics, these sensors allow robotic grippers to pick up fragile items like fruits, vegetables, or thin-walled containers without crushing them.
Human-Robot Collaboration
As robots move out of cages and onto the factory floor alongside humans, safety becomes the priority. Touchence provides the tactile "skin" that makes robots aware of their surroundings. This technology is also applied in service robotics, where robots interact with people in hospitals, nursing homes, and retail environments.
Medical and Healthcare
Touchence technology is increasingly explored for medical applications. This includes tactile feedback for robotic-assisted surgery, where a surgeon needs to "feel" the stiffness of tissue through a remote interface, and in nursing care robots that must lift or move patients gently and securely.
Research and Development
The company remains a primary supplier for academic and corporate research labs worldwide. By providing reliable, off-the-shelf tactile sensors, Touchence has lowered the barrier to entry for developing advanced manipulation algorithms and soft robotics.
Market Position and Strategic Impact
Touchence Inc. sits at the intersection of material science, electronics, and artificial intelligence. By digitizing the sense of touch, they provide the raw data necessary for AI models to learn "physical intuition." As the robotics industry shifts toward "Soft Robotics"â??machines made of compliant materialsâ??Touchenceâ??s flexible sensing arrays are becoming indispensable. Their presence in the Japanese market, a global hub for robotics manufacturing (housing companies like Fanuc, Yaskawa, and Kawasaki), allows them to collaborate closely with the world's leading robot manufacturers to define the next generation of automated systems.
