Multi-Sensory Feedback Systems

Sensory feedback is not a “nice-to-have”. If it doesn’t stay on the skin, it doesn’t exist. This Scientific Reports paper “Ultra-conformable tattoo electrodes for providing sensory feedback via transcutaneous electrical nerve stimulation” tackles a very practical bottleneck in non-invasive neurostimulation: standard wet Ag/AgCl electrodes don’t adapt well to irregular residual-limb surfaces and can detach during movement. :contentReference Their proposal is elegant: ultra-conformable, Paryylene C–based “tattoo” electrodes to deliver somatotopic sensations via TENS, without surgery. :contentReference. A few details: • impedance stability over a working-day window: max variation ~8% over 9 hours at the target stimulation frequency :contentReference; • comparison on 12 participants: no significant differences vs wet Ag/AgCl in rheobase (p>0.3) and chronaxie (p>0.15), and comparable sensory perceptions :contentReference; • lower operational impedance with tattoo electrodes (practical advantage for real use) :contentReference. It’s about making non-invasive sensory feedback less fragile and more wearable, the kind of detail that determines whether feedback can live outside the lab. 📝 Link in the first comment. Question for those working with stimulation/wearables: what is the real blocker for daily-life TENS feedback today: adhesion, selectivity, skin comfort, or long-term stability? #haptics #sensoryfeedback #tens #transcutaneousstimulation #neuroprosthetics #prosthetics #upperlimbprosthesis #somatosensory #somatotopy #wearables #epidermalelectronics #electrodes #tattooelectrodes #parylenec #biomedicalengineering #rehabilitation #assistivetechnology #humanmachineinterface #embodiment #neuroengineering

𝗧𝗵𝗲 𝗔𝗻𝗮𝗹𝗼𝗴𝘆: 𝗪𝗵𝗲𝗻 𝗦𝗶𝗹𝗲𝗻𝗰𝗲 𝗜𝘀 𝗮 𝗦𝗶𝗴𝗻𝗮𝗹 In aviation, the black box records everything—data, audio, pressure changes—so investigators can understand not just what happened, but why. In healthcare, we have patient surveys. Complaint reports. Staff notes. But let’s be honest: most of the experience data we gather is either delayed, sanitized, or incomplete. 𝗪𝗵𝗮𝘁 𝗶𝗳 𝗼𝘂𝗿 𝗵𝗼𝘀𝗽𝗶𝘁𝗮𝗹𝘀 𝗵𝗮𝗱 𝗮 “𝗯𝗹𝗮𝗰𝗸 𝗯𝗼𝘅” 𝗳𝗼𝗿 𝗽𝗮𝘁𝗶𝗲𝗻𝘁 𝗲𝘅𝗽𝗲𝗿𝗶𝗲𝗻𝗰𝗲? A real-time, multi-sensory, always-on record of what patients go through, beyond what they tell us in a form? 𝗧𝗵𝗲 𝗚𝗮𝗽𝘀 𝗪𝗲 𝗗𝗼𝗻'𝘁 𝗧𝗮𝗹𝗸 𝗔𝗯𝗼𝘂𝘁 We assume feedback = reality. But here’s what we may be missing: • Patients who never speak up: due to fear, cultural norms, or low expectations • Body language in waiting rooms or during discharge conversations • Non-verbal drop-offs: appointment no-shows, cancelled follow-ups, or early discharges • Tone and emotion in call center interactions rarely captured or analyzed • “Too late” feedback: Post-discharge surveys don’t help today’s patient 𝗧𝗵𝗶𝗻𝗸 𝗗𝗶𝗳𝗳𝗲𝗿𝗲𝗻𝘁𝗹𝘆: 𝗘𝘅𝗽𝗲𝗿𝗶𝗲𝗻𝗰𝗲 𝗦𝗲𝗻𝘀𝗶𝗻𝗴 𝗙𝗿𝗮𝗺𝗲𝘄𝗼𝗿𝗸 To create a true PX Black Box, we need to blend different modes to unlock different insights - Passive Signals: No-shows, long wait room times, silent exits - Emotional distress, friction, avoidance - Environmental Cues: Noise levels, seating patterns, eye contact - Discomfort, safety perception - Behavioral Feedback: Staff-patient micro-interactions - Empathy, tone, relational experience - Active Listening: Surveys, complaints, social media, interviews - Verbalized perceptions and emotions 𝗥𝗲𝗮𝗹-𝗪𝗼𝗿𝗹𝗱 𝗔𝗽𝗽𝗹𝗶𝗰𝗮𝘁𝗶𝗼𝗻𝘀 • Use AI sentiment analysis on call recordings & WhatsApp messages • Create a “𝙋𝙓 𝙎𝙝𝙖𝙙𝙤𝙬𝙞𝙣𝙜 𝙋𝙧𝙤𝙜𝙧𝙖𝙢” where staff silently observe journeys end-to-end • Equip waiting areas with PX Observers who map emotion, not just time • Integrate “𝙎𝙞𝙡𝙚𝙣𝙩 𝙀𝙭𝙞𝙩 𝙄𝙣𝙩𝙚𝙧𝙫𝙞𝙚𝙬𝙨” via digital kiosks no names, no pressure • Correlate EHR behavior patterns with patient satisfaction dips 𝗬𝗼𝘂𝗿 𝗣𝗫 𝗟𝗮𝗯 𝗘𝘅𝗲𝗿𝗰𝗶𝘀𝗲 Reflect on these 3 questions as a Leader or PX Leader: 1. What patient experiences in my hospital are invisible to our current systems? 2. How often do we act on what’s not said rather than what’s measured? 3. What could we learn by simply observing one full patient journey in silence? 𝗙𝗶𝗻𝗮𝗹 𝗧𝗵𝗼𝘂𝗴𝗵𝘁 Experience is not just data it’s signals. The future of PX leadership lies in sensing the invisible and decoding the unspoken.                    𝗜𝘁’𝘀 𝘁𝗶𝗺𝗲 𝘄𝗲 𝗯𝘂𝗶𝗹𝘁 𝗼𝘂𝗿 𝗼𝘄𝗻 𝗯𝗹𝗮𝗰𝗸 𝗯𝗼𝘅𝗲𝘀.

China has developed an advanced electronic skin that allows humanoid robots to sense pressure, temperature, and physical damage—enabling reactions similar to human pain responses. This breakthrough significantly enhances robotic awareness, safety, and interaction capability. The electronic skin is composed of flexible layers embedded with thousands of sensors that detect touch, force, heat, and sharp impacts. When excessive pressure or damage is detected, signals are instantly sent to the robot’s control system, triggering reflex-like reactions such as pulling away or adjusting grip strength. Pain perception in robots is not about suffering but protection. By detecting harmful conditions early, robots can prevent self-damage, handle fragile objects more carefully, and operate safely alongside humans. This is especially critical for robots used in healthcare, manufacturing, and public environments. The technology also improves learning. Feedback from the electronic skin allows robots to refine movements over time, similar to how humans learn through sensory experience. This results in better precision, adaptability, and durability. This development represents a step toward robots that are not just intelligent, but physically aware. As humanoid robots become more integrated into society, such sensory systems will be essential for safe and effective human-robot collaboration.

I am pleased to highlight the recent achievements of Dr SHI Ge, who completed his PhD at UCL Mechanical Engineering/UCL and is now a researcher at the Commonwealth Scientific and Industrial Research Organisation (CSIRO's Data61). SHI Ge's latest publication in the IEEE Transactions on Haptics (#ToH) presents a novel multi-cavity haptic feedback system. This system utilises a purely hydraulic-based approach that detects physical touch and delivers directional feedback through a fingertip sensor, paving the way for enhanced tactile interaction capabilities. Read the full article here: https://lnkd.in/enVR2CG5. This research builds upon his prior work on fluidic haptic interfaces for mechano-tactile feedback, previously published in the IEEE Transactions on Haptics (https://lnkd.in/edMDUntD), and modelled using finite deformation theory, which was featured in #SoftMatter Journal by The Royal Society of Chemistry. Read the full article here: https://lnkd.in/eNN87kfz In collaboration with Dr Jialei Shi, who graduated from UCL Mechanical Engineering/UCL earlier in the year and is now with the Hamlyn Centre for Robotic Surgery at Imperial College London, they developed a flexible, soft robotic handheld laparoscopic device, driven by this innovative multi-cavity touch interface. This work has been published in IEEE Transactions on Medical Robotics and Bionics (#TMRB): https://lnkd.in/eFVHB6Cd. This impactful research has been supported by UCL Grand Challenges, the EPSRC (grant number: EP/V01062X/1), and UCL-Indian Institute of Technology, Delhi Seed Funding 2020-21. #Haptics #Robotics #Research #Innovation #UCL #MedicalRobotics #IEEE

Most robots rely only on vision, making force-heavy tasks difficult; this system lets users feel forces directly w/o extra sensors: [Project & Paper ⬇️] FACTR combines force feedback with smart training, helping robots adapt to real-world interactions more like humans. Why this matters: ✅ Uses force feedback for better control in tasks that need precision ✅ Learns faster with a training method that prevents over-reliance on vision ✅ Improves performance on new objects by 43 percent compared to other methods ✅ Works with a simple, low-cost teleoperation system for better data collection FACTR makes robots better at handling real-world objects by teaching them to feel, not just see.

Touch is the final frontier for the intersection of robotics & artificial intelligence, and a recent advance has shown how close we are getting to solving one of the main challenge: smart manipulation. Today’s humanoid hands are learning to sense, adapt, and collaborate with a nuance that rivals biology, and AgiBot World and FlexiRay have shown that distributed, multimodal tactile arrays that cover fingertips, phalanges, and palms, can process over a million manipulation trajectories, enabling robots to outperform previous dexterity benchmarks by 30% and achieve 2x task success rates when tactile feedback is integrated. We are seeing these sort of improvements at @analog devices as well, in our pioneering work in multimodal dexterous AI solutions. These systems process tactile data in parallel and adapt to new objects and tasks in real time, with the richness of sensory feedback as the key element. The labs and companies building these capabilities now are setting the standard for the next wave of human–robot collaboration. #TactileSensing #DexterousRobotics #HumanRobotInteraction #RoboticsResearch #AIManipulation https://lnkd.in/eRq84Cjs

Designing for the senses, how do you trick the brain into believing what it sees? In XR the secret to immersion lies in human perception. Sight, sound, touch and even smell work together to convince your brain that the virtual is real. But here’s the challenge: if these sensory inputs aren’t perfectly synchronized, the illusion breaks. A delayed sound or mismatched haptic feedback? Suddenly, you’re reminded it’s all just pixels and code. So, how do designers achieve harmony? 🔹 Visuals: High resolution, smooth motion, and minimal latency. 🔹 Audio: Spatial soundscapes that match what you see. 🔹 Touch: Haptic feedback that mirrors real-world sensations. 🔹 Smell & Taste: Emerging areas for deeper immersion in the future. The key is balance, too much stimulation can overwhelm users, while lag or inconsistency breaks the experience entirely. Curious about how XR designers pull this off? I’ve broken it down further in my latest article.
