“…In the convex parts, the skin and the material have good contact, but in the concave parts, the lack of contact leads to absent pressure. 45 The average values of P max and E max are 1.57 AE 0.55 kPa and -20.5 AE 4.2%, respectively. The pressure measured near the anterior superior iliac spine at the waistband is 3.18-5.14 kPa.…”

With the development of society and increasing demands, the design of male underwear should conform to human ergonomics. However, some special delicate aspects related to morphological features of the male body need to use computer technologies for generating a digital replica of real bodies, with textile materials instead of real objects from the perspective of satisfying increasing needs. This article aims to apply three-dimensional (3D) simulation technology in compression clothes design. We have proposed the method of material precision simulation, body avatar establishment, and virtual underwear design. In this study, multiple 3D software to establish avatars of male bodies with different morphological features are used first. Secondly, the conversion of the Kawabata Evaluation System for Fabrics results in a digital library of knitted materials to be explored, which are mainly based on elastic characteristics and compression performances. Then, we conducted a series of try-on tests with average size avatars, which are created using 3D scanning technology, and evaluated the pressure and comfort using a new method we recommended. Finally, the results of the virtual and actual tests are compared. All digital replicas achieve the same results as the real ones. This study can promote the application of 3D simulation technology in male compression underwear design by operating a digital replica instead of real objects.

“…The bladder was then inflated by a hand-operated air-pump and the pressure inside the bladder was measured with the VLCM connected in series with the air-pump. The principle behind this set up was to apply pressure onto the sensor surface due to the expansion of the bladder [ 27 ]. While the pressure inside the bladder is equivalent to the external pressure applied on to the sensor, to avoid any error which could be caused due to the deformation of the bladder at its edges or any irregularity triggered by the inflation of the bladder, it was decided to position the sensor in the middle of the bladder.…”

The aim of the publication is to report the accuracy, repeatability and the linearity of three commercially available interface pressure measurement systems employed in the treatment of venous disease. The advances in the treatment and management of chronic venous disease by compression therapy have led to considerable research interest in interface pressure measurement systems capable of measuring low-pressure ranges (10–60 mmHg). The application of a graduated pressure profile is key for the treatment of chronic venous disease which is achieved by using compression bandages or stockings; the required pressure profiles are defined in standards (BSI, RAL-GZ, or AFNOR) for different conditions. However, achieving the recommended pressure levels and its accuracy is still deemed to be a challenge. Thus, it is vital to choose a suitable pressure measurement system with high accuracy of interface pressure. The authors investigated the sensing performance of three commercially available different pressure sensors: two pneumatic based (AMI and PicoPress®) and one piezoresistive (FlexiForce®) pressure sensors, with extensive experimental work on their performance in terms of linearity, repeatability, and accuracy. Both pneumatic based pressure measurement systems have shown higher accuracy in comparison to the flexible piezoresistive pressure sensors.

“…[ 58 ] Hakala et al. [ 59–61 ] developed a compression garment using bladders and micropumps as actuation mechanisms, Figure . The main objective of the study was to observe graduated compression and its control, and to improve conventional PCDs by using smaller and lighter components that did not hinder motion or require the patient to remain still during treatment.…”

Venous leg ulcers can have significant social and economic impacts, and are generally treated by applying compression to the lower limb, which aids in promoting blood return to the heart. Compression therapies commonly involve the use of passive bandages that suffer from issues associated with incorrect application, and although automated solutions have begun to appear; these are often bulky and hinder mobility. Emerging microtechnologies and new materials enable the development of "smart" compression therapy devices, which are defined as systems that use miniaturized and lightweight actuators and electronics to control the applied pressure. This paper reviews the state of the art in smart compression therapy research. A total of seventeen different devices has been identified, categorized as using one of three actuation mechanisms: pneumatic compression, motor-driven mechanisms, and smart materials (including shape memory alloys, shape memory polymers, and electroactive polymers). The field is still in its relative infancy and further refinements are required to create mass manufacturable compression dressing systems that meet medical, ergonomic, and economic standards. The use of miniaturized actuators has immense potential for the development of smart compression dressings, which will ultimately lead to higher compliance, increased patient comfort, enhanced mobility, and better treatment outcomes.
