In the past few years, we have covered plenty of smart prosthetic hands that make life easier for amputees. The INDY hand is also worth a look. It has a stainless steel, aluminum, and polyamide construction, weighing only 350 grams. It can be used for plenty of daily tasks, whether it is getting dressed, picking small items or exercising.

The INDY hand has touchscreen friendly fingers. You can customize this prosthesis with your phone. You can also use it to view EMG activity. This prosthetic arm can be personalized in different colors. More information is available here.

Meet the TrueLimb Prosthetic Arm: a bionic arm with independent finger joints that move in tandem with 6 adaptive grips. It uses vibration cues to give you the sensation of touch. This bionic arm is designed to match the tone of your skin.

You can use this bionic arm all day on battery and charge it via USB-C. It uses 36 sensors in its sockets to provide 360-degree coverage. It is 3D printed with PA12 nylon and weighs 1.5 pounds. More info is available here.

There are plenty of advanced robotic hands for amputees these days. Researchers are always looking to make them more responsive and lightweight. Engineers at MIT and Shanghai Jiao Tong University have designed a soft, lightweight artificial limb that provides users real-time tactile control.

This smart hand weighs about 0.5 pound. It is made with components around $500. Its design looks similar to the robot from the film Big Hero 6. It is made with EcoFlex and has a 3D printed palm.

In the past few years, we have covered a bunch of wearable devices that let users control robots and drones with hand gestures. UC Berkley Researches have come up with a new device with wearable biosensors that relies on AI software to recognize gestures a person intends to make based on electrical signal patterns in the forearm. Conductive hydrogel is then applied to each of the 64 electrodes.

The user has to perform each gesture once for machine training. This wearable can be used to control robots and prosthetic arms. Pretty neat, don’t you think?

Meet Adam’s Hand: a fully adaptive bionic hand that helps amputees live a more independent life. It uses one motor to move all the fingers, making them adapt to grasped objects’ shape and size. This IP44 rated prosthetic hand is powered by a ThunderCell battery and uses a low power, active EMG electrodes to read your muscular signals.

This bionic hand comes with Bluetooth connectivity and an app for calibration and training your muscles using a virtual model. You can find out more about it here.

Meet the HandMorph: a passive exoskeleton with haptic feedback that miniaturizes grasp. It uses mechanical links to transmit motion to the wearer’s fingers. It has 5 tiny anatomically correct fingers. So why build something like this? HandMorph lets researchers test things with the grasping range of a child.

Jun Nishida, Soichiro Matsuda, Hiroshi Matsui, Shan-Yuan Teng, Ziwei Liu, Kenji Suzuki, and Pedro Lopes are behind this idea.

Prosthetic legs are getting more advanced all the time. Plenty of researchers are working to make them more comfortable for their users. Biomechatronics researcher Roman Stolyarov has developed a terrain-adaptive control system for robotic leg prostheses that helps people with amputees get mobile and walk seamlessly with smooth transition between foot positions.

As he explains:

I developed a way to control a robotic prosthesis such that it allows the user to walk more naturally across different ground terrains. Besides increasing mobility and comfort, this control system also makes walking more symmetrical, decreases the risk of falling, and diminishes impacts on biological joints.

Meet the Zeus Hand: a bionic limb with 12 grip modes and 2 customizable grip modes to make life easier for amputees. It has a silicone glove with 10 color options for you to choose from. EMG electrodes are used for signal processing and gain adjustment.

This bionic hand has compliant fingers and opposable thumb. It has 5 individually articulated digits that let users manipulate objects of varying types and shapes. Zeus has a a max closing time of 1.5 seconds and grip force of 152N. It has a flexible battery pack with magnetic charging.

Here is another robotic exoskeleton designed to take load off of workers. The 4th generation Clay X can help workers when they lift loads up to 28kg. It comes integrated with cloud and can connect to the internet of things and smart factories.

This bionic suit can be connected to a smart factory ecosystem using standard APIs. It lasts up to 8 hours on battery. It takes the load off workers to reduce unnecessary stress on their body.

There are already a bunch of exoskeletons being tested by manufacturers and the military to can reduce load no workers and soldiers. Muscle Suit Every is a wearable exoskeleton that uses air pressure to take load off your body. It is suitable for lifting, farm work, and shoveling snow.

Muscle Suit Every is IP56 water resistant. It is ideal for -30 to 50C conditions. This exoskeleton doesn’t require any battery to work. It “uses the air pump at the waist to fill the suit with air and stabilize strength at your core where it is most effective, simultaneously supporting your back and thighs as you transport heavy loads.”

Here is an exoskeleton designed to take load off soldiers. Lockheed Martin’s ONYX Exoskeleton is a powered lower-body device that increases mobility and reduces fatigue. ONYX conforms to the human body and has sensors that read speed, direction, and angle of movement to an on-board computer that drive electro-mechanical actuators at the knees.

ONYX reduces the energy needed to squat, kneel, and move. It simply reduces stress on leg muscles and increases ability to handle rough terrain and stairs.
