The SynTouch BioTac is a multimodal tactile sensor based on a biomimetic design mimicking the human fingertip. A flexible silicone skin filled with conductive fluid replicates skin mechanoreceptors. The sensor simultaneously measures: electrical impedance distribution (19 electrodes), 3-axis force, vibration, and temperature and its changes. Interface: SPI. Connector footprint compatible with standard robotic fingertip mounts.
BioTac was widely used in research robotics, delicate object manipulation, and hand prosthetics. SynTouch ceased operations around 2022 — product discontinued (EOL). Dimensions: ⌀ 15.5 × 36 mm. Normal force range: 0–35 N.
Tactile Sensor · serves as: Sensing, Manipulation, Research and Education.
Which group SynTouch BioTac belongs to and how it is built
Sensors is a broad subcategory of hardware components responsible for collecting data from a robot's environment, mechanisms, and electronic systems. It encompasses distance, position, pressure, temperature, voltage, current, contact, and numerous other sensor types. This subcategory applies when a component is sensory in nature but does not belong to a more specific group such as LiDAR or Vision Components.
A tactile sensor is designed to detect physical contact, pressure, force distribution, and other touch-related properties. In robotics, it is particularly important in dexterous hands, grippers, manipulators, and human–robot interaction systems. It enables contact detection, grasp force control, pressure distribution recognition, and improved manipulation precision and safety. Tactile sensors are a key component in the development of haptic perception and more natural robot–environment interaction.
